In late 2013, trap kings Flosstradamus headed to the studio in Atlanta to get #plurnt with a bunch of the city's finest rappers and producers. Basically, it turned into a party and out of it came a grip of tunes, including Floss' most recent mega-single "Mosh Pit," featuring call-to-rage vocals from Casino.Watch this video to see how Kurt and Josh operate behind the scenes and how Casino turned the whole goddamn studio into a mosh pit. Oh yeah, and weed. Lots of weed."Mosh Pit" is out now on Ultra, with an instrumental and remix pack coming soon. Buy it here.
