With La Roux’s irresistible “Bulletproof” now a bona-fide hit on the charts, flame-haired vocalist Elly Jackson fires up her high-pitched vox once more, trading in her thin, 80s-style synths for the slick production of Diplo and Switch (of Major Lazer fame). La Roux and Major Lazer have teamed up for a free, star-studded mixtape, Lazerproof — which you can download here. It’s an instant sensation: more than 200,000 people tried to grab it this morning.

We have been DYING to hear this collaboration, since these two acts separately put on two of the most incredible sets at Coachella—while you’re waiting for the download, head below to hear a few of the tracks and check our pics of the performances by Major Lazer and La Roux. The 14-song collection features such guests as Amanda Blank, Gucci Mane, Opal, Gyptian, Rusko and BET Awards nominee Drake—not to mention some classy hot Iron Man-inspired cover art.
