I made a thread just like this a while ago, it'll turn 2 trash trust me. Oh well here are my 2 cents

The Roots,Jay Z, Lil John(if you can stand the horrible music, and just pay attention to the strippers, which i can't) Black Star, its remarkable to see Twista spit the same exact why he does in the studio live,Eminem, and everybody needs to see Public Enemy perform at least once
