Mighty Marty Perez, the rock photographer, grew up in Chicago, but got his start in Seattle in the crucial late '80s, as the American independent scene flourished; Perez became the court shooter for the fabulous Young Fresh Fellows. Then he moved back to Chicago, where he shot the strange pop doings there in the mid-1990s. Friendly and unpretentious, Perez flourished as a tireless chronicler of the mosh pit and the implacable face of the rock proletariat, fixing with an unblinking eye on everything from the deranged assault of the Jesus Lizard to the brittle celebrity of Liz Phair. Perez will be in town next week at the behest of the Mission's Aquarius Records, where an exhibit of Perez's work, "Liver Than You'll Ever Be," opens with a reception Tuesday, Feb. 24, from 6:30 to 8 p.m. Aquarius is at 1055 Valencia (at 22nd Street). Admission is free; the show will be up through May 1. Call 647-2272 for more information.
