With their unique electronic spin on the African kuduro genre, Portuguese group Buraka Som Sistema helped kick off the main stage on Friday with an energetic and wholly funky set that had the crowd immediately grooving. Also, they feature a Portuguese producer who also calls himself "Li'l John," setting up the possibility of an amazing fight somewhere down the line with pimp cup icon (and Steve Aoki BFF) Li'l Jon. We'll have to wait and see on that one.
