Umphrey’s McGee and STS9 will livestream their joint show at Chicago’s Northerly Island this Saturday, August 17. The stream will begin at 6:30pm CT with the opening set from Up Until Now, with STS9 coming on at 7pm and Umphrey’s McGee taking the stage at 9:15pm.

The stream will be broadcast via TourGigs & StageIt as a pay-per-view, which can be purchased for $13.

In addition, both bands will be giving away goodies to those who “tip” the most during the event. Fans will be able to get tickets to Umphrey’s McGee’s New Year’s run, the 2014 Summer Camp Music Festival or the Life Is Beautiful Festival. They will also be giving out autographed setlists, autographed vinyl, merch, downloads and the opportunity to have Ryan Stasik on your voicemail.
