Mad Decent’s free weekly single project, Jeffree’s, just released this insane pair of bass tracks from Brooklyn producer Baauer. “Harlem Shake” has been a mainstay on Radio 1′s Diplo and Friends show and was featured on Rustie’s Essential Mix, propelled by an up-close sonar synth that could mix straight into actual harlem shake-era minor classics, like G-Dep’s similarly-patterned “Special Delivery.” The song and its bright, rap-in-the-rainforest B-side, “Yaow,” are up for free download, with a higher bit rate version available for subscribers of Mad Decent Premium.
