Actually I dont think it's free. If you click the tickets link above, you can check out prices....I dunno. I cant tell if the regular tickets are sold out or if you just only have to pay for VIP?? And I wouldnt rush too hard to see Mos. I saw him last week at the artists ball and he's was way off his game.
