The Sisters Morales, Lisa and Roberta, combine folk, pop and traditional Mexican music. The Tucson, Arizona natives began singing at ages 5 and 6, respectively, when their father would literally make them "sing for their supper" with mariachi groups at restaurants. The two eventually started showcasing their eclectic mix of blues, mariachi, pop and rock around Tucson. With a lineup that included Lisa's husband, David Spencer on guitar, the group relocated to San Antonio and formed Luna Records for the 1997 release of "Ain't No Perfect Diamond." In 2002, the sisters honored their mother with the all Spanish-language album, "Para Gloria."
