The mysterious –and current trap sensation–?Z, was recently in LA working with Red Bull Studios on a mixtape entitled BallTrap Muzic Vol. 1 which gave the producer the opportunity to collaborate with high-caliber artists such as Casey Veggies, Trinidad James, Iamsu!, Problem, Trae Tha Truth and more. Never before seen footage of the sessions were released today via TrillHD and you can watch the visual below. Some incredible music was certainly made in those sessions and BallTrap Muzic Vol. 1 can’t drop soon enought!
