The Mimi Fishman Foundation has teamed up with the WaterWheel Foundation to launch a new online charity auction that offers Phish fans a chance to bid for tickets to stops on the band’s upcoming fall tour, including their Halloween run in Las Vegas.

The auction features a series of ticket packages including two GA passes, along with a CD of the show, to Phish’s shows in Albany, NY; Hampton, VA; Nashville, TN; Rosemont, IL; and Las Vegas, when the group will celebrate Halloween with four nights at the MGM Grand Garden Arena.

See the full auction, which runs until this Monday, September 24, here.
