AIDS in Stages Latin Hustle explores the cult of Selena and traces the ominous transformation of burritos into "wraps" in Full Frontal Rudity, a three-man show about all things Latino, queer, and funny. Theirs is the first performance in the weeklong Latino/a AIDS Theater Festival, now in its fifth year and slated to run concurrently with the eighth annual AIDS Theater Festival and the 10th National AIDS Update Conference held at the Civic Auditorium. Artistic Director Hank Tavera credits a disproportionate rise in HIV and AIDS among Latinos as a reason for the Mission-Castro offshoot of the downtown festival, as well as the need for a little levity. Safe sex is the theme at the second night's show, "We Will Survive," a bilingual drag spectacle (10:30 p.m. Wednesday at Esta Noche, 3079 16th St. at Mission; $5), while playwright Erin Cressida-Wilson's piece about coming of age in the city, The Changing Face, shares the bill with Sean San Jose's Pieces of the Quilt and Ya Vas, Carnal, a one-man work by Culture Clash's Herbert Siguenza at a two-night performance marathon (8:30 p.m. Thursday and Friday at Theater Rhinoceros, 2926 16th St. at South Van Ness; $5). Juan Roca's comic play El Baul de las Maravillas (The Marvelous Chest) closes the festival (8:30 p.m. Saturday at Theater Rhino). Latin Hustle's performance tonight benefits LLEGO California at 8:30 p.m. at Josie's Cabaret & Juice Joint, 3583 16th St. (at Market), S.F. Admission is a $10-15 donation; call 554-8436.
