Though many equate punk rock with the Ramones and CBGB, Los Angeles boasted its own vibrant scene in the late 1970s and early '80s, as is documented in "The Beautiful & the Damned." This new exhibition of photographs by Ann Summa includes portraits of such bands as the Germs, the Screamers and the Cramps. Exene Cervenka, of the legendary L.A. punk band X, will perform an acoustic set and join Summa for a book signing at a special reception Saturday evening. Track 16 Gallery, 2525 Michigan Ave., Santa Monica. Noon-6 p.m. Thurs. and Fri. Noon-9 p.m. Sat. (opening reception 6-9 p.m.) (310) 264-4678. http://www.track16.com.
