There’s far more to electronic dance music than the stuff heard at megaraves in Berlin. The Portugal-based Buraka Som Sistema melds all styles of dance music from the world’s depressed urban centers, sampling from techno, rap, baile funk, dubstep, Angolan kuduro, and beyond. Hailing from Buraca, a Lisbon suburb with a large immigrant population, the group includes rapper/producer Conductor (a Cuban raised in Angola), vocalist Kalaf Angelo (from Angola), DJ/producer J-Wow (from Portugal), percussionist/producer DJ Riot (from Portugal), and various guest MCs and dancers. On its albums, Buraka Som Sistema jettisons most acoustic elements in favor of a laptop approach. M.I.A. guested on its debut LP, Black Diamond, and helped establish the band’s M.O.: chanted vocals over frenetic beats and blings. On its second album, 2011’s Komba, the title track celebrates the dead with a bit of church organ; “Candonga” plays with Afro-Cuban percussion and sirens. Be ready for even more stimulus overload tonight: They might bring water guns. Buraka Som Sistema performs with Willy Joy at 7 p.m. at U Street Music Hall, 1115 U St. NW. $15. ustreetmusichall.com.
