I don't think I've been to an Ozfest, but I have been to an Ozzy concert years ago, and he is worth seeing live for sure. For some of you who have not yet gotten a chance to go out and see many concerts, you will learn that some artists are great in the studio but suck at live performances. There are some who may suck in the studio, but kick but at live performances. No matter what genre of music you may prefer, you are only cheating yourself if you don't at least expose yourself to some different stuff, and use your mind for goodness sake, don't let nobody tell you what is good and what sucks.
