There is seemingly no end to the number of artists associated with the East End, past and present. Annual exhibitions that attempt to bring more of them to our attention should be commended for giving us a fuller picture of the creativity that has existed in our midst for more than a century.This year’s East End Collected, the fifth, will open on Saturday at the Southampton Arts Center. Organized by Paton Miller, a Southampton artist, the show brings together familiar and lesser-known names in a mix of about 30 or so artists that is usually revelatory.According to Mr. Miller, more than 150 artists have participated in the franchise, which was started soon after Southampton Village took over the space once occupied by the Parrish Art Museum. At the time, he told village officials that “a new arts center had to be loved by the community to be enthusiastically supported and have a chance to grow.” He suggested that the center see itself as a mirror reflecting the regional artistic community.This year’s roster includes Casey Chalem Anderson, Michael Cardacino, Sylvia Channing, Jeremy Dennis, Madison Fender, Francine Fleischer, Lori Hawkins, Carol Hunt, Anna Jurinich, Christine Keefe, Suzanne LaFleur, Geralyne Lewandowski, John Margaritis, Alexis Martino, Lauren Matzen, Eric Meola, Oscar Molina, Joan Lee Montefusco, Nika Nesgoda, Cindy Pease Roe, Jay Schneiderman, Arden Scott, Ty Stroudsburg, Trina Tozzi Michne, and Isabel Turban.In addition to these artistic “veterans,” Mr. Miller has put together a de facto junior committee of artists at the beginning of their careers. The E.E.C. Jr. group consists of Harlan Beeton, Emily Esposito, Kyle McNamara, Cian O’Neill, Kai Parcher-Charles, Finn Pilaro, and J.B. Riffaud.A reception will be held on Saturday from 5 to 7 p.m. While the show is up, the center will continue its free artist Hangouts nights at which those attending can socialize with the artists who have work on view, have a glass of wine, and even play Ping-Pong in the galleries. They are scheduled for next Thursday and May 30 from 6 to 8 p.m.Free gallery tours with Mr. Miller and the artists will take place on May 19 and June 9 at 12:30 p.m. Mr. Miller will host an illustrated talk featuring the artists on June 2 at 4 p.m. The show will remain on view through June 9.
