This is being announced Monday. If they don't book the Chicago date during Lolla again (they did this last year and then cancelled the show due to lack of ticket sales) I'd probably go depending who is on the lineup.
Lineup announced. Everclear, Live, Filter, Sponge. Not one of those bands is even close to an original lineup (Live is the closest but they're missing their lead singer, they're essentially a Live cover band now), plus no Chicago stop makes this an easy skip for me.
