Buraka Som Sistema has become a European sensation, thanks to their unique take on kuduro, a strain of dance music from Luanda, Angola. Most recently, the band has worked with M.I.A. to produce the song "Sound of Kuduro," currently making the rounds on YouTube and their newest album, Black Diamond. Kuduro originated with resourceful Angolan DJs—who managed to turn free computer sample sounds from outdated PCs into some of the most kick-ass and energetic dance music around.
