The young up and coming rapper from Pittsburgh named Mac Miller @MacMiller was recently spotted ZShock'n. Shout out to John Geiger @GeigerGeiger, he tweeted & spotlighted this Youtube video of Mac Miller going off in a Concert he had. Make sure you get Mac Miller's new K.I.D.S. mixtape, we were impressed and keep it in rotation here at the ZShock HQ. Stay ZShock'n!
