Guadalupe Rosales, “Echoes of a Collective Memory,” at the Vincent Price Art Museum. For years, the Los Angeles artist has been building an archive of ephemera related to Chicano youth culture: studio portraits, informal snapshots, fliers, magazines, mix tapes and other objects. In her first solo museum show, she is employing these in installations that examine the both the intimate and public ways in which SoCal youth have historically connected over fashion, music, cruising, raves and backyard parties. The exhibition will include video, collages and an altar to the memory of a cousin lost to gang violence. Through Jan. 19. East Los Angeles College, 1301 Cesar Chavez Ave., Monterey Park, vincentpriceartmuseum.org.
