Grupo Mazz was formed in Brownsville, TX, by singer/guitarists Jimmy González and Joe López, and emerged as one of the most innovative bands in their genre after adding synthesizer to combine traditional Mexican music and popular Latin rhythms. They debuted in 1978 with Mazz, featuring the hit single "Comprendo Mi Amor." During the following decades, Grupo Mazz became a successful band on the regional Mexican scene, climbing the charts with "Laura Ya No Vive Aqui" and "Porque Te Quiero," among other songs. In 1999, the group's leading members decided to go on their own, assembling two different bands, Jimmy González y el Grupo Mazz and Joe López y La Nueva Imagen Mazz. ~ Drago Bonacich
