Umphreys McGee will wrap up a summer on the road with two shows at Chicagos Navy Pier over Labor Day weekend. The Mimi Fishman Foundation is working with the group to raise charitable donations in conjunction with these performances. Auctions are now underway for two tickets, after-show passes and a band-signed poster for each of the September 3 and 4 gigs. In addition, a third auction will feature all of the above plus a thirty minute guitar lesson from UMs Jake Cinninger before the Sunday show. Bidding is now underway and will continue through August 28.
