Big Gigantic performed at Chicago’s Lollapalooza this past weekend. Now that the festival is over and they are past their radius clause, the group confirmed on their next Chicago show on Facebook. Big G will headline Chicago’s Aragon Ballroom on December 31. The livetronica duo started something of a Chicago New Year’s Eve traditional when they performed at The Riviera last year. Big Gigantic will perform at San Francisco, CA’s Outsidelands Music Festival this weekend.
