“Due to a family matter, Scott Metzger will not be able to join us in Chicago for the planned Bustle in your Hedgerow Lollapalooza aftershow on Sunday August 6th. However, don’t be alarmed, Dave, Marco and Joe have confirmed a very special guest performer sitting in for Scott for one night only. We are thrilled to have this guest on board for what is sure to be a special occasion…see y’all in Chi-town on Sunday. Still haven’t picked up your tickets for this one yet? Don’t sleep on it, head over to SilverWrapper.com to buy your’s today.” [Benevento/Russo Duo]

I’m guessing Trey. Anyone got any other ideas?

Update: Confirmed. Brendan Bayliss from Umphrey’s McGee will be the special guest. Snatch up ‘dem tix!
