If you missed Troy Ave tearing down the Fool’s Gold party in Austin yelling “POWDERRR” earlier this spring, now’s your chance to get caught up. Download his new mixtape Bricks In My Backpack 3 featuring guest spots from the likes of Fabolous, Action Bronson, and Chase N Cashe, then come thru Drom on Friday for the release party, with DJ sets from Nick Catchdubs and more. Flyer after the jump.
