A pioneer of Chicano rock 'n' roll, Rubén Funkahuatl Guevara recounts his life in music, performance art and activism — from his time as lead singer of the doo-wop band The Apollo Brothers, his collaborations with Frank Zappa and Cheech Marin, and his crossover into the Chicano performance art world of the 1960s and 1970s — all of which shaped Mexican American culture.
