Because Halloween falls on a Wednesday this year, most festivities kick off this weekend. Check out Martyrs' two-day concert event Halloweekend, in which a dozen local bands (six on Friday, six on Saturday) perform in character as various bands from the 70s and 80s.
At the Barnes and Noble in Skokie, editors and writers from the Onion, America's finest news source, will be on hand to discuss and sign copies of The Onion Book of Known Knowledge: A Definitive Encyclopaedia of Existing Information, a send-up of reference tomes worldwide.
Rick Springfield—yes, that Rick Springfield—performs at Joe's on Weed Street because why the hell not?
