Buraka Som Sistema has become a European sensation, thanks to its unique take on kuduro, a strain of dance music from in Luanda, Angola. The genre originated with resourceful Angolan DJs, who managed to turn free computer sample sounds from outdated PCs into some of the most kick-ass and energetic dance music around. Earlier this year, the band worked with M.I.A. to produce the song “Sound of Kuduro,” and more recently released its debut album, Black Diamond.
