After two critically acclaimed but only moderately selling albums, los Lobos
were hired to record songs for the film biography of Hispanic '50s rocker Ritchie Valens
, resulting in this soundtrack album, which, in addition to eight los Lobos
recordings, features tracks by Marshall Crenshaw
, Brian Setzer
, and others. Los Lobos
' remake of the title song topped the charts, as did this album, which went on to sell two million copies. The result has been something of a career dilemma for the band, who went back to being a critically acclaimed, modest seller afterward.
