Mazz is a Grammy Award–winning Tejano band originating from Brownsville, Texas. Formed in the early to mid-1970s by Jimmy González and Joe López, the group emerged as one of the most innovative Tejano crossover bands after adding synthesizer to combine traditional Tex-Mex, Mexican music, and popular Latin rhythms.

In 1978, Mazz released the self-titled album, 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 hits "Laura Ya No Vive Aqui" and "No Te Olvidaré," among other songs. Lopez, with his suave voice, and Gonzalez, with his winning songwriting and producing talents, formed separate groups in 1998: Joe Lopez y La Nueva Imagen Mazz and Jimmy Gonzalez y Grupo Mazz. Lopez also teamed up with Selena's brother, on the 2004 album A.B. Quintanilla III Presents Joe Lopez.
