Remember once upon a time, when cumbia was just a lilting, shuffling little folkloric rhythm? Yeah, we don't, either. But the stuff this DJ duo makes sounds like cumbia hopped in a Delorean, went to the future and came back to find everything changed. It's still the same warm, familiar rhythm we know and love, just ... different, somehow. That shuffle is screwed and chopped, diced up and hot-glued back together with bits of dub, kuduro, baile funk, dancehall, hip-hop, and a whole sticky mess of house-y, techno-laced electro-beats. "Murga del Guachin" is ready for your next party playlist.
