La Compagnia Amarilli, a vocal duo formed in New York City in 2013, will perform “Rosa Mystica,” a concert featuring music by Pergolesi, Monteverdi, Schutz, and Telemann, at St. Ann’s Episcopal Church in Bridgehampton on Saturday at 5 p.m.

Kinga Cserjési, a soprano, and Deborah Carmichael, a mezzo-soprano, will be accompanied by a string quartet and an organ continuo. Highlights of the program include Pergolesi’s “Stabat Mater” and motets by Monteverdi and Schutz.

Admission is free, with contributions welcomed.

For the third consecutive Labor Day weekend, the Parrish Art Museum in Water Mill will present an evening of bluegrass and barbecue with the Ebony Hillbillies, tomorrow from 5 to 8 p.m. on its covered terrace.

The Hillbillies, who have performed at Carnegie Hall, Lincoln Center, international music festivals, and on “Good Morning America,” are proponents of the 19th-century American string dance band tradition that gave rise to jazz, blues, bluegrass, rockabilly, and rock’n’ roll.

The Golden Pear Cafe at the museum will offer a Southern-themed barbecue buffet, local wines and craft beers, and special cocktails. Guests are encouraged to take lawn chairs and blankets and to dance if the spirit moves them. Tickets are $10, free for members, students, and children.

The Watermill Center has announced its roster of artists in residence for September through January. Each artist will spend two to six weeks at the center to create collaborative works that investigate and challenge the norms of performance.

Selected artists are Oliver Beer from the United Kingdom, Amy Khoshbin of the United States, Cirkus Cirkor from Sweden, Manuela Infante with Teatro de Chile, from Chile, and Carlos Soto from the U.S. Each will hold an open rehearsal, with Mr. Beer’s scheduled for Sept. 26. All rehearsals are free, but advance reservations are required.

The Neo-Political Cowgirls’ “Eve,” a dance-theater performance during which the audience wanders at will through an 11-room set, will have its premiere from Sunday through Oct. 1 at The Gym at Judson, at 243 Thompson Street in Manhattan.

The Cowgirls, under the direction of Kate Mueth, are dedicated to developing innovative theatrical works that celebrate the female voice. “Eve” is about a “perfect woman” created by the mad “Maker” in a world already rife with experiences and history. Moving through the set, the audience watches her story unfold through music, movement, and art.

Tickets, which are $35, can be ordered at brownpapertickets.com.

The vocalists Bobby Peterson and Joy Jones, joined by Jessica Harika, will perform a selection of piano solos, musical theater, opera, and spirituals tomorrow evening at 7 at Hoie Hall, the parish house of St. Luke’s Episcopal Church in East Hampton. The concert is free and open to the public.

The Conservative Synagogue of the Hamptons will present “Music Talks,” a concert and discussion by Elad Kabilio, an Israeli cellist, on Saturday at 8:30 p.m. at the social hall of Queen of Most Holy Rosary Church in Bridgehampton.

Mr. Kabilio, accompanied on piano by Benjamin Laude, will perform a range of music from the traditional Kol Nidre to a contemporary Israeli setting of Kaddish. He will also lead a discussion of the music’s spiritual significance. The Selichot service, with cello accompaniment, will take place from 10:15 to 11:15 p.m.

The 15th annual Box Art Auction benefiting East End Hospice will be held Sept. 12 from 4:30 to 7 p.m. at the Ross School Lower Campus Field House in Bridgehampton. For those who wish a sneak peek, the boxes are on view today from 10 a.m. to 4 p.m. at Hoie Hall at St. Luke’s Episcopal Church in East Hampton.

Three of the artists offered an early look at their boxes at various stages of development. James DeMartis, who works in metal, has taken part in 13 of the events. “Every year I do something different,” he said. He decided on a jewelry box with a bronze base for this year’s auction, and several months ago he showed a visitor a mock-up before beginning work on the actual piece.

Over the course of fabrication he cut shapes out of the bronze, enriched the surface with chemicals, and welded the pieces of the base from the inside with sheet metal. The box was oiled and waxed and partitioned to define jewelry space. Mr. DeMartis, who admitted to a history of finishing his pieces at the last minute, had to sneak into Hoie Hall after dark the night before last year’s preview to deposit his box.

Since April Gornik usually paints on such a large scale, she has to rethink how to approach something as small as a standard cigar box. “This year I’m doing a reflection of a pond,” she said several months ago. She had an image picked out and began working on it over the summer. Ms. Gornik, too, has participated in many of the box art auctions. “Working on such a different scale can be a challenge,” she said, “but the important thing is that I really believe in the hospice and supporting its work.”

Michelle Stuart’s body of work includes earthworks, installations, encaustic paintings, drawings, prints, and photographs. She has cited as influences on her practice history, botany, travel, and astronomy, the latter reflected in her choice of a starry night sky from which, somewhat mysteriously, a hand emerges. The photographs of her work in progress make clear how she is able to synthesize disparate objects and materials into a coherent whole.

The first box art auction took place 15 years ago, when more than 100 East End artists were asked to transform small, unadorned boxes into unique works of art to be put up for bids at an auction to benefit the hospice, which provides care for terminally ill patients, their families, and loved ones.

Arlene Bujese, the benefit’s chairwoman, has organized the art for this year’s exhibition, as she has for the past 13 years. Michael Cinque will serve as master of ceremonies, and Lucas Hunt will conduct the auction. Leif Hope will receive the Spirit of Community Award at the auction for his contributions to the area for more than 50 years.

Among the more than 80 artists participating this year are Jennifer Cross, Mr. DeMartis, Connie Fox, Ms. Gornik, Carol Hunt, Dennis Leri, Christa Maiwald, Fulvio Massi, Randall Rosenthal, Ms. Stuart, Hans Van de Bovenkamp, and Frank Wimberley.

Admission to the auction is $75, which includes wine and hors d’oeuvres. Photographs of the boxes will be available for viewing at eeh.org.

Marder at Marder

A show of recent work by Mica Marder will open at the Silas Marder Gallery in Bridgehampton on Saturday, with a reception from 4 to 8 p.m. It will continue through Oct. 17.

The works in the exhibition reflect Mr. Marder’s ongoing exploration of the East End’s coastal wildlife in a series of large-scale assemblages in which he repurposes discarded objects into the form of a fin, a tail, a cheek, or an eye. In some, the raw materials, such as a small anchor, a piece of charred wood, or a broken clam rake, retain their identity, while in others Mr. Marder works the surface with paint to flatten and camouflage them. Recent works on paper and oil paintings will also be on view.

Two Shows at Ille

Ille Arts in Amagansett will present two exhibitions, “Ken Collins: Portals, Time and Place” and “Literary Vision: New Works by Marc Francois Auboire and Barry McCallion,” from Saturday through Sept. 22. A reception will take place Saturday from 5 to 7.

Mr. Collins’s photographs reflect, in his words, “the ongoing flux between the atmospheric, the graphic, the figurative, and the abstract. I seek to inspire prolonged viewing that invites contradictory readings and perceptions of what is typically seen.”

Mr. Auboire, who lives and works in Paris, paints book covers, creating singular compositions of colors and language. Mr. McCallion’s handmade books are unique editions, each page crafted of materials and mediums that fit the spirit of the book. He lives in Springs.

Artists on Film

In conjunction with the exhibition “Elaine de Kooning Portrayed,” this year’s Artists on Film series at the Pollock-Krasner House in Springs, which will launch tomorrow at 7 p.m., will focus on portraiture. Marion Wolberg Weiss, a film historian and art critic, will introduce the programs and lead discussions after the screenings.

Tomorrow’s program will include Gerald McCarthy’s “E de K: A Portrait,” in which, while painting, the artist discusses her themes and preoccupations; “An Elaine de Kooning Tribute,” Max Scott’s memorial tribute that makes use of archival footage from LTV, and Rudy Burckhardt’s “Dogwood Maiden,” a comic fantasy in which de Kooning stars as The Sorceress.

Subsequent films are “The Picture of Dorian Gray,” a 1945 adaptation of the classic Oscar Wilde tale (Sept. 11), Shirley Clarke’s 1967 film “Portrait of Jason,” in which a male hustler expounds on being black and gay in 1960s America (Sept. 18), and Alfred Hitchcock’s “Vertigo,” in which a portrait reinforces the director’s recurring themes of the double and voyeurism (Sept. 25).

“The Light Within”

“Lumen Naturae: The Light Within the Darkness of Nature,” an exhibition of paintings by Sheryl Budnik, will be on view at the Romany Kramoris Gallery in Sag Harbor from today through Sept. 24, with a reception set for Saturday from 5 to 6:30 p.m.

The title of the show refers to Paracelsus’s idea that knowledge springs from light. Ms. Budnik’s paintings aim to capture “the immensity and power of nature itself,” according to the artist. Many are recognizable as landscapes or seascapes, while others are more purely abstract, but all are linked by their emphasis on the physical presence of paint.

At Ashawagh Hall

“Components,” an exhibition of work by Bob Bachler and James Kennedy, will be on view Saturday through Monday at Ashawagh Hall in Springs, bringing the two artists within a stone’s throw of their late Surface Library Gallery and Atelier, which moved to New York City in 2011 after five years on Fireplace Road.

Mr. Kennedy’s recent paintings explore the linguistics of music, mathematics, dance, and architecture with a personal abstract vocabulary that seeks to solve “spatial equations through paint.” Mr. Bachler’s ceramics range from the functional to the sculptural, and the work in this exhibition focuses on constructs that converse with the forms in Mr. Kennedy’s work.

The gallery will be open Saturday from 10 a.m. to 8 p.m., with a reception from 5 to 8. Sunday and Monday hours will be 11 to 6. In celebration of Labor Day, the Job Potter and the Friends band will perform on Ashawagh Green Sunday from 6 to 8 p.m.

Two at Halsey Mckay

Concurrent exhibitions of recent work by Rachel Foullon and Johannes VanDerBeek are on view at the Halsey Mckay Gallery in East Hampton now through Sept. 20.

Ms. Foullon uses a variety of objects and materials, including rope, strapping, pulleys, fabrics, and wood, among others, to create sculptural objects and installations.

The paintings in “Tahitian Hallucination,” Mr. VanDerBeek’s show, use elemental forms of landscape imagery, such as leaves and branches, that are transformed into more abstract configurations of pattern and shape through the density of clay, paint, and oil stick that are pushed into plastic molds.

Under Water at White Room

The sea will be the subject of the next exhibition at the White Room Gallery in Bridgehampton, which will open Tuesday and run through Oct. 5. A reception for the two featured artists, Mike Laptew and Savio Mizzi, will happen Sept. 12 from 6 to 8 p.m.

Mr. Laptew is an underwater photographer and cinematographer who has selected for this exhibition seascapes of flowing kelp, sea grass, rock formations, blue crabs, lobsters, schools of striped bass, and many others, some taken off Shinnecock, Montauk, or Fire Island.

Mr. Mizzi is a painter, illustrator, and furniture-maker who lives and works in East Hampton. While his paintings include portraits, animals, and landscapes, sometimes with Surrealist overtones, this show will feature paintings of fish, other local marine life, and the coasts.

“From London to Havana”

“From London to Havana: Rock and the Rhythm,” a show of photographs by Steve Joester, will open Saturday at Lawrence Fine Art in East Hampton and continue through Sept. 30.

A noted rock ’n’ roll photographer who has worked with the Rolling Stones, Bob Marley, Pink Floyd, the Police, and many other iconic bands, Ms. Joester, a British subject, has visited Cuba often and photographed Old Havana many times since the 1990s.

According to Howard Shapiro, the gallery’s director, “We wanted to illustrate the contrast of the frenetic, almost chaotic Western cultural world with a place that has been practically suspended in time.”

Woodbine Collection in Montauk

The Woodbine Collection, a year-round gallery that opened in Montauk in May, is currently showing paintings by Kristy Schopper, sculpture by Luke Schumacher and Isabelle Radtke, and ceramics by Melanie Schopper. Exhibitions of work drawn from its collection of more than 30 artists will change on a regular basis. The gallery is open daily except Tuesdays.

Labor Day Show

The Southampton Artists Association is holding its Labor Day art exhibition today through Sept. 13 at the Levitas Center for the Arts at the Southampton Cultural Center. A reception will be held Saturday from 4 to 6 p.m.

Scott Christopherson and Brad Barber were editing their film “Peace Officer,” a documentary about the militarization of America’s police forces, when, on Aug. 9, 2014, Michael Brown was killed by a policeman in Ferguson, Mo.

“We thought we were finished filming,” Mr. Barber recalled, “but Ferguson caused us to add one more shoot to the schedule. We thought it was important to talk to some experts to contextualize the problem, particularly to acknowledge how much more this happens in communities of color.”

“Peace Officer,” which will be shown at Guild Hall tomorrow at 7:30 p.m. as part of the Hamptons International Film Festival’s SummerDocs series, opens with rough, black-and-white footage of a SWAT team in action. The film cuts to William (Dub) Lawrence, a former marine, police officer, county commissioner, and sheriff who now makes his living repairing water and sewer pumps. Mr. Lawrence presents the details of the shooting we have just seen and his subsequent independent investigation.

Brian Wood, a fireman in Farmington, Utah — and Mr. Lawrence’s son-in-law — was killed outside his house in 2008 by a SWAT team from the Davis County Sheriff’s Office after a long standoff during which the only person Wood aimed a gun at was himself. It turns out Mr. Lawrence, who witnessed the incident, founded the local SWAT team in the 1970s after being elected Davis County sheriff at the age of 29.

The film follows his obsessive quest to bring to light the truth, not only behind his son-in-law’s shooting but also behind several other police raids in neighboring communities. Mr. Lawrence is a compelling, ingratiating figure whose determination to illuminate the militarization of America’s police forces is matched by the meticulousness of his investigations and the clarity of his explanations. The filmmakers discovered him and his story almost by chance.

“I knew Dub’s son,” said Mr. Christopherson. “I didn’t really know Dub, but he knew I was a documentary film professor, and he approached me to see if I would teach him how to edit. He showed me his own two-hour edit of his son-in-law’s shooting death with police footage and photographs, and I was blown away by the story, which I knew about but hadn’t followed too closely when it happened.”

While a law officer, Mr. Lawrence investigated 125 major felony cases and helped break the Ted Bundy case. His intention, in forming the Davis County SWAT team, was to use it to neutralize violent situations. At that time there were approximately 50 SWAT raids per year in the United States. By 2005 there were 50,000 such raids annually. The reason for the increase was not more crime, but increased police access to military weapons.

The 1033 program, created by the National Defense Authorization Act of fiscal year 1997, authorized the military to give equipment to police departments. While several spokespeople from law enforcement argue that SWAT teams aim to prevent violence, the film makes it clear that most of the no-knock raids, which are usually conducted at night, target nonviolent and consensual crimes such as taking or dealing drugs and give rise to the violence they are supposed to prevent.

One especially brutal incident, which led to an intense gun battle, targeted Matthew Stewart, whose crime was growing marijuana in his basement. Stewart was accused of killing a policeman during the raid, which was conducted at night by officers in plain clothes, but Mr. Lawrence’s detailed reconstruction of the incident casts doubt on the police version. Stewart hung himself in jail before his case could go to trial.

Alec Baldwin, the series host, will lead a post-screening discussion with the filmmakers. “Peace Officer” will have its theatrical release in New York City on Sept. 16, in Los Angeles on Sept. 18, and will be broadcast next May as part of the PBS series “Independent Lens.”

The Montauk Library will present a musical change of pace on Wednesday at 7:30 p.m., with a free performance by the Raggle Taggle Gypsy-O’s Celtic band.

From traditional Celtic fiddle music to contemporary Irish folk to the Pogues, a Celtic punk band, the group performs a wide range of Irish music as well as American folk, bluegrass, and country music. Made up of four veteran musicians from New York City, the band features soaring vocal harmonies and virtuoso instrument playing.
