A Grupo Mazz song is recognizable from its beginning alone: Dreamy synths float behind a bittersweet melody, as drums start tapping out a syncopated beat; then, the smooth, rich voice of Jimmy Gonzalez enters, singing about a new love or a recent heartbreak. The band have honed their Tejano cumbia sound since the mid-'80s, rising to prominence with hits like “Dame un Minuto” and “Quien Iba a Pensar,” while “A Pesar de Todo” adds optimistic horns to the mix. “Mazz Polkitas” even experiments with upbeat polka, reflecting the cultural diversity of Gonzalez's Texas home.
