At the recent L.A. stop HotNewHipHop host Jen DeLeon briefly spoke to the producer of the moment. Mustard just dropped off his new album ’10 Summers’ and so they spoke to him about narrowing down the final tracklist, his album cover art, why he chose to let the LP go for free, who he wants to collaborate with that he hasn’t yet (he names John Mayer and Calvin Harris) and more.
