After identity politics, then what? I'd expect some fireworks from this discussion because it's led by Seattle artist/resident firecracker Mary Ann Peters. It goes along with the blazing group show at the gallery, I.D.: Individual Demographics, in which artists such as Glenn Ligon, Jack Daws, Kara Walker, Kerry James Marshall, Tom of Finland, Alice Wheeler, and John Waters explore what it means to be defined. Peters's cotalkers are Ki Gottberg, playwright and Seattle University drama professor, and artists John Feodorov and Margot Quan Knight. (Greg Kucera Gallery, 212 Third Ave S, 624-0770. 7 pm, free.)
