Good news for fans of rippling posteriors: Major Lazer, Diplo‘s dancehall alter ego, has unleashed a new single guaranteed to cause a booty-quake when spun at the local spot. On Bubble Butt, the heavyweight DJ/producer’s stark, body-moving boardwork backs contributions from a somewhat strangely-matched trio of guests. In addition to vocals by Atlantic/Elektra pop hitmaker Bruno Mars, the record packs freaky flowed bars by Jamaican dancer/recording artist Mystic and YMCMB rhymesayer Tyga. Featuring this ass-shaking anthem, previous single Jah No Partial and many more club-ready selections, Free the Universe is scheduled to hit record stores and online retailers April 16.
