This Mexico City quartet isn't just one of the more daring and creative bands of the rock en espanol movement, it is one of the more daring and creative bands to come out of any country during the alternative-rock boom of the 1990s. Café Tacvba's idiosyncratic collision of modern pop styles (from rock to hip-hop and electronica) with Latin folk traditions (including mariachi, ranchera, tejano, banda, and samba) is unlike anything in rock's rich, colorful history. Despite Café Tacvba's eclecticism and innovative use of instrumental textures, this music doesn't come off as schizophrenic. The group's distinctive sound is funneled through the grainy vocals of dynamic frontman Ruben Albarran, who sings with a bratty punk sneer at one moment and a gentle coo the next.
