Understood but I would also point out you made a thread while at the festival not really enthusiastic about seeing his set and expecting it to suck and then proceeded to walk out during Daughters which usually is not even midway through his show.
Did you even get a chance to rock out to Made You Look? Hate Me Now? Got Yourself (when DJ Green Lantern flips the Deep Cover blend)? Nas is Like? A few people I've seen on twitter and tumblr seem to have enjoyed his set from their comments
Dont me wrong I've seen him a few times (and Jay a few times) and both have floored me (God Son UK tour, Disant Relatives, the Arena show, HHID show, Jay during the Black Album, the orchestra at Kingdom Come tour, WTT) and underwhelmed me at different points (God Son NYC concert on DVD, the New Orleans show, Jay at SXSW last year) but I would definetly not say he's the worst preformer I've seen (Hello Rick Ross, Cam'ron) and I'd put him up there with KRS-One, Redman and Method Man, Lil Wayne (Surprisingly good), Busta as some of the memorable shows. Depends on how many rap shows you got to and your expectation and if you really wanna see the guy (Which I feel you didnt want to anyway)
