Mexican-American sisters Lisa and Roberta Morales grew up in Tucson, AZ, learning to sing traditional Mexican music and developing their own brand of pop. They separated after high school, but in 1989, when Roberta came in to sing background vocals for a band Lisa had formed, they began performing together again. They added Lisa's husband, guitarist David Spencer, drummer Rick Richards, and bassist Larry Evans to fill out their backup group. After moving to Houston, they attracted interest from the country music establishment in Nashville, but ultimately opted for an independent path, releasing their debut album, Ain't No Perfect Diamond, on their own Luna Records label in October 1997. Someplace Far Away from Here, another combination of English and Spanish songs, followed in 1999. In 2002, by now based in San Antonio, the sisters released their third album, Para Gloria, an all-Spanish-language set dedicated to their mother.
