The Brat  was a Chicano punk rock ensemble originating from the barrios of the East Los Angeles, California.  Its three core members consisted of lead singer Teresa Covarrubias, lead guitarist Rudy Medina, and Bass player Sidney Medina.  From their conception in 1979 to their eventual break-up in 1985, The Brat contributed to the customization and intermeshing of multiple musical and cultural models that culminated in the distinct East Los Angeles, Chican@ punk sound.   (More from Wikipedia)
