Major Lazer and La Roux
LAZERPROOF
La Roux, the British synth-pop duo, and Major Lazer, a hipster dancehall vanity project helmed by producer-DJs Diplo and Switch, don't share any obvious aesthetics. But their respective bodies of work -- just one 2009 LP, each -- are a jumping-off point for "Lazerproof," a mix tape as chaotic as it is cohesive. Like M.I.A.'s Diplo-helmed "Piracy Funds Terrorism, Volume 1" mix tape, it succeeds by acting more like a broad survey of emerging music trends than a compilation of remixes and mash-ups.
