Lollapallooza is storming The Bastion and invading Chicago tonight through August 6, and Chicago comedy is making its presence felt at the ginormous rock festival.

Second City will be running the Mindfield Stage, where, according to Chicagoist: "A mix of Mainstage, e.t.c., and Touring Company performers will make sweet, funny music (it is Perry Farrell’s party, after all) and go interactive with their audience. They’ve also got a prank or two up their sleeves and some viral videos on their projector."

We also heard that random Second City cast members will be roaming around the festival, to perform pranky interactive bits with concertgoers. Hope they're going to film some of that; it could lead to some hilarious moments. (Or some "interactivity" with the Chicago Police Department.)

i.O. West 15-man troupe Mission Improvable (who originally formed at i.O. here in Chi-town) will be doing their thing Friday, Saturday & Sunday, from 3-3:45.

Second City also invited longtime local favorites Schadenfreude to entertain the moshing masses, and Schad-man Justin Kaufmann tells us that they'll be "introducing the Alderman Ed Bus Tumblers, our version of the Jesse White Tumblers...our tumblers are out of shape and they do burpees instead of flips." They will be onstage Friday and Saturday from 6-6:45.

Go! Rock it out! Say hi to Jane for us while you're there.
