Latin rock band Maria Fatal became one of Los Angeles' rock en español scene pioneers in the early '90s. Formed by brothers Gabriel, Ernesto, and Fernando Ramírez, and joined by bass player Pepe Alonso, the group started playing in Mexico City's club circuit before moving to the U.S., debuting with a self-titled album released by San Francisco-based Aztlán Records. That same year, Maria Fatal participated in Austin's South by South West Music Seminar, while their song "Portate Mal," was climbing on Latin charts.
