Dave Matthews Band announced today that the Allman Brothers Band will be its opening act at the Sept. 8 show in Atlanta. Warehouse members can buy tickets and VIP passes starting tomorrow at 9 a.m. Unlike the typical Warehouse ticketing system, this is a presale on a first-come, first-served basis.

Tickets cost $45 and VIP passes, which include early entry into the park, an exclusive viewing area and other perks, are $250. The show will take place in Piedmont Park and benefit the Piedmont Park Conservancy. Members of the conservancy also have access to the presale.
