Never been to oz fest but i did go to warped tour once.. out of 3 bands I wanted to see I saw one, and thats b/c the stages are about 1/8 mile or more apart and you need a bloody golf cart to get about. and the one band i did see A7X was so bad live.
The best shows i've been to are the small venues.. NYHC ... Hardcore bands know how to put on a show.seen HATEBREED many times and the pit was always great. Saw Candiria 2 times and both times the pit was like WWIII bodys flying blood on the ground, bouncers came out bloody and wooozy.. Good times LOL..
Oh and TOOL.. THEY ARE SICK!!!!! OMG BATMAN!! if you can go see them live DO IT!!!!
