What started off as a touring alt-rock mecca for the pierced and flannel-wearing has found its way handily in the new millenium by morphing into a one-weekend-only extravaganza in the Midwest. Perry Farrell's Lollapalooza show now takes place every summer in Chicago (the Tribune has good coverage,) and boasts a laundry list of rock and pop acts that a touring show probably couldn't support what with artist's time constraints and egos.
The 2010 version of the show has landed the now-obiquitous Lady Gaga, as well as pop-punk pioneers Green Day, and grunge forefathers Soundgarden. This is where I tell you that my mom wouldn't let me go to see Soundgarden play at this same show in 1993 and it's haunted me ever since.

Also scheduled: Arcade Fire, MGMT, Phoenix, Jimmy Cliff, the Black Keys, and DEVO, for us old people. And not for nothing, single-day tickets are a wallet-draining 90 bucks. If you want to go for all three days of porta-potties and smelly-revelers expect to lay down $215.
