I went to the lollapalooza last year and it was the greatest concert i had ever been to. the format was great. no matter what the bands are coming go. the atmosphere is awesome. its a full 8 hours of rock and popular music. bands last year: Audioslave, Janes Addiction, Perfect Circle, INCUBUS, Rooney, Jurrasic 5, and more all at one concert! its all outside so its not crowded at all. neone been to it? Oh ya, dont diss Earth Wind & Fire....they are the shit.
