Tomorrow devout music nerds will celebrate one of our newer high holidays, Record Store Day, where indie stores will offer live music and goodies to remind people that iTunes isn’t the end-all and be-all of the music-buying experience. All participating stores will be offering treats like limited-edition records from the likes of Steve Malkmus and Vampire Weekend, but a few are pretty much daring you not to spend your entire Saturday afternoon in a record store.

Permanent Records is offering in-store performances by locals Purricane and buzz band Grand Ole Party at around 3 PM, with a visually enhanced multi-boombox listening party for the Flaming Lips’ uber-psychy four-CD set, Zaireeka. (In case you’re one of those people who didn’t care about the Flaming Lips yet in 1997, that’s the one where you’re supposed to listen to the discs all at once.)

At Reckless’s Wicker Park location there’s an in-store by Rogue Wave at 5 PM, and freelance mind-wizard Steve Krakow–the guy behind the Plastic Crimewave Sound, Galactic Zoo Dossier, and the Reader‘s own Secret History of Chicago Music comic–will be drawing rock ‘n’ roll caricatures on demand from noon till 6 PM.

Both the Grand Ole Party/Rogue Wave shows at Schubas this weekend are sold out, so if you don’t already have tickets these will be your only opportunities to catch them this time out.

Record Breakers at 2109 S. State is going balls-out with a ton of live performances–American Draft, Amplified Heat, Chicago Green Counterpunch, Daphne Willis, Doppler Shift, Green Sugar, Hot Garbage, How Far Too Often, KB Duo, Lorimer Sound, Moving Targets, Ronnie Rock & Blues, Seth McGaha, Sonny’s Dog, Sybris, We Are the Willows, White Devil, Power Space, Too Sweet, the Fastest Kid Alive–as well as free hot dogs and 20 percent off everything they sell. That is some serious Record Store Day spirit.
