Across their career, this Portuguese group furiously burrow into the seams between electro, techno, hip-hop, zouk and kuduro. Beyond dance-floor fusions, Buraka Som Sistema push into spacey EDM territory on “Voodoo Love” and pretzel the titular woodwind in “Zouk Flute” beyond recognition. The band are also bold enough about their rhythms to flip an EKG beep into the cardiac kick of “Macumba”.
