“Underwater Dreams,” a 2014 documentary about the sons of undocumented Mexican immigrants who create a robot from Home Depot products, will be shown at the Parrish Art Museum in Water Mill tomorrow at 6 p.m.

On a whim, two high school science teachers entered their school in an underwater robotics competition sponsored by NASA and the Office of Naval Research. Four students fashioned Stinky the robot, in part with PVC pipe and duct tape, and their creation defeated M.I.T. in the competition.

Tickets are $12, free for members and students.

“Love Letters,” the A.R. Gurney play in which two characters, Melissa and Andrew, sit side by side reading letters, notes, and cards that span nearly 50 years of their separated lives, will be performed by Andrew Botsford and Jane Baldwin on Saturday at 2 p.m. at the Southampton Inn.

  The free program, which is being presented by the Rogers Memorial Library, the Southampton Historical Museum, and the inn, will be followed by a reception. The inn is taking reservations at 631-283-6500.

The Chickpeas, an East End all-female vocal ensemble, will perform a free concert at the Montauk Community Church Coffeehouse tomorrow at 7 p.m.

Consisting of Marcia Previti, Jane Hastay, Deb Coen, Lisa Shaw, and Elizabeth Sarfati, the group will perform “After the Gold Rush,” “How Can I Keep From Singing,” “Lullaby,” “Wings of a Dove,” and several other tunes. Their music is sung a cappella or with piano accompaniment by Ms. Hastay.

The local action of the 2017 campaign of One Billion Rising, a mass international demonstration launched five years ago to end violence against women, will be presented in Guild Hall’s JDTLab series on Sunday at 2 p.m.

The Wamponamon Masonic Lodge No. 437, which was established in Sag Harbor in 1858, has been off limits to nonmembers for as long as anyone can remember, save for a single open house last June when the public was invited to see the painted Masonic symbols and celestial imagery on the inner sanctum’s walls and the domed ceiling by John Capello, an artist and member of the Masonic Brotherhood. 

That day, it turns out, was not the one and only opportunity to visit the lodge, as Patrick McErlean, its Worshipful Master, had hinted to The Star last year. On Saturday at 8 p.m., the lodge will host the first of a winter music series, with a concert by Rafaela Gurtler, a jazz vocalist and flutist who grew up in Sag Harbor. 

“It’s a really nice space,” Mr. McErlean said last week, “so we figured, why not use it?” Another event in the series will be a performance by a string quartet, he said, and the Masons may host poetry and other readings as well. 

Four events are planned for the music series, which will conclude in the spring. If they prove popular, “we’ll do them through the fall and winter” next year, Mr. McErlean said, possibly doubling the number of performances in the space, which is not air-conditioned and does not host meetings in the summer. 

Ms. Gurtler, who lives in East Hampton, is a cantor at Most Holy Trinity Catholic Church in East Hampton. Last week she promised “a little Valentine’s Day concert” on Saturday, and while the song selection remains a secret, those attending can expect a rendition of the popular jazz standard “My Funny Valentine.” Wayne Sabella and Richie Scollo will accompany her on piano and saxophone respectively.  

Mr. McErlean said last year that he hoped to revive interest in the Masons and add new members to the lodge, which was once a hub of the community. More members, he said, would add muscle to the group’s charitable efforts. 

“We give money to the food bank . . . we could give a bigger scholarship to a local high school student. We’re trying to find our own way of fund-raising that would be both interesting and bring people from the community into the lodge. It would be nice to get members. At the same time, it’s such a beautiful space, and it’s nice to let people come in and see it, and use it.” 

Tickets to Saturday night’s concert at Wamponamon Masonic Lodge, at 200 Main Street in Sag Harbor, are $20. Refreshments will be served.

Karyn Mannix Contemporary and the White Room Gallery in Bridgehampton will present the “12th Annual Love and Passion: The Dirty Dozen Art Show” tomorrow through Sunday at the gallery, with a wine reception to be held Saturday from 5 to 8 p.m.

Running time for the animated films is 90 minutes, 130 for the live action films. Tickets are $14 per individual screening, $24 per program, $12 and $20 for HIFF members.

The Southampton Arts Center will present “Beneath the Underdog: The Music of Charles Mingus” on Saturday at 7 p.m. Selections from Mr. Mingus’s music will be performed by Claes Brondal on drums, Bob Hovey on trombone, Santi Debriano on bass, Eric Schugren on saxophone, and Bill Smith on piano.

Mingus, the legendary bass player who died in 1979, is one of the essential composers and performers in the history of jazz. “Beneath the Underdog” was his celebrated memoir. 

Tickets are $15, and the doors will open at 6:30 for refreshments from Union Cantina. The program has been organized by the Jam Session, whose frequent home is Bay Burger in Sag Harbor.

In Process @ the Watermill Center will provide an opportunity for engagement with Cleek Schrey and Gillian Walsh, two of the center’s artists in residence, on Saturday from 2 to 4 p.m.

A fiddler, improviser, and composer from Virginia, Mr. Schrey is developing a new work during his residency using electronics and his own unique instrument, a custom-built violin with 10 strings.

Ms. Walsh, an artist and performer from Brooklyn, is collaborating at the center with the writer Emily Hoffman on a new work that applies choreographic thinking to a technological landscape. 

The event is free, but reservations are required.

Chris Bauer, an actor from Sag Harbor, is co-starring with Lawrence Gillard Jr., Jordan Lage, and Rebecca Pidgeon in “The Penitent,” a new play by David Mamet that premiered yesterday at the Atlantic Theater Company in Manhattan and will run through March 19.

Mr. Bauer plays a renowned psychiatrist who is asked to testify on behalf of a young patient. When he refuses, his career, ethics, and faith are thrown into question.

Among Mr. Bauer’s many credits are starring roles in HBO’s “True Blood” and “The Wire.” He recently appeared in the award-winning FX series “The People vs. O.J. Simpson,” and his film credits include Clint Eastwood’s “Sully” and Jodie Foster’s “Money Monster.”

 A former trustee of Bay Street Theater, Mr. Bauer has worked with Mr. Mamet on the West Coast premiere of the playwright’s “Race” and the Bay Street production of his “Romance.”
