I've seen him live. He sucks. Basically he had the worst opening acts ever and came on the stage like an hour late. I'm not a huge fan of him, but I am a serious hip hop/rap fan and I don't hate some of his songs. Well, he was soo much worse live than he was on his albums/mixtapes. He kept repeating and repeating his hooks which suuuuuck. It was like "ink my body, ink my body, ink my body" like two thousand times or whatever the shity three word hook was on whatever song he was doing. Plus all his songs are retarded and have nooooo lyrical content at all. His music just gets straight boring. He defines mindless hip hop. And hes a mixtape rapper so all his beats suck too.
Wiz has some alright singles but he was just terrible in concert. Theres so many better rappers out there to go see.
