2009 was a good year for Buraka Som Sistema. The Lisbon, Portugal-based crew put progressive kuduro on the map in 2007 with their M.I.A.-assisted track “Sound of Kuduro” and spent the past year promoting their acclaimed 2008 studio debut, Black Diamond, with electric live shows that can only be described as epic.  Their electro Afro-funk sound, soca rhythms, and—of course—kuduro-rave energy has swept the club scene around the world, so it’s no surprise that London’s legendary Fabric nightclub would call on BSS to head up FabricLive 49. “The bass keeps coming, and coming, and coming and coming... and going and going and going and drops,” we’re informed on “Hey.” And drop it, they do; BSS assembles a mix that wades through grimy dubstep, electro, dancehall, Peruvian funk and features artists from across the globe—Angola, Portugal, France, Jamaica, Peru and the UK, among others.
