Competition for top honors in this category was fierce. As the informal capital of Latin America, Miami-Dade has an ample assortment of música del sur. But Conjunto Progreso makes a hell of a strong case. A Cuban jam band through and through, Conjunto offers sumptuous son that any of the masters might envy. With multiple vocalists, guitar, bass, piano, bongos, congas, trumpets, tres, clave, cowbell (for which we have a fever — the only cure being more cowbell), and guiro (which actually has nothing to do with Jersey Shore), Conjunto is a full-blown orchestra. And the band sounds like it. Much like Tula leaving the candle on in her room, the descargas they throw down at all of their frequent local gigs could be deemed a fire hazard. They seriously light it up.
