There are some who may only know Denise Gale from her five-year stint as host of “Drinks With Denise” on LTV, where she mixed it up with local chefs and personalities over cocktails and wine. They might not realize that lurking under the tipsy banter and awkward conversational transitions was a serious abstract painter, who pursued her metier first under the tutelage of Peter Plagens in California, and then in New York City before settling in Springs in 2001. Mr. Plagens, well known for his criticism in The Wall Street Journal and other publications, is also a painter, and an admirer of Ms. Gale, who appeared on a short list of painters he respects in ARTPULSE magazine.
