Mos Def is not just an artist his great musician no doubt about that, and we don’t except him to be dope on each and every performance, but on Sat he was very average. I mean we don’t except him to have the same kinda feel or energy he had with Black Star or on Black on Both Sides. Mina personally I feel that he could have gotten away with it if his track selection was good, tracks that ppl know him of, I don’t agree with the saying that it was alright for him not to perform his common hits/cla**ics. I believe that if u an artist performing to the crowd that u have never performed in front of before, u Mos Definitely need to perform your album hits/cla**ics. Masta Ace when he was here, he took us back to the days of Juice Crew hits, Sittin on Chrome album hits….up until current material… joints. He should have done it the same way as he did his performance on Dave Chappelle’s block party.
