Dark Star Orchestra will once again give fans a chance to request songs at its upcoming GratefulFest performance. In an effort to aid research for Rett Syndrome, a neurological disorder which is currently incurable, Dark Star will be auctioning off song requests and variety of other prizes. Last years GratefulFest performance included an appearance by Keller Williams and David Gans, as well as a run through the rarely covered 1987 Dylan and the Dead stadium tour. Internet requests will be accepted and Dark Star wishes to remind its fans that stuffing the ballot box is encouraged. As previously reported, GratefulFest will take from August 19-21 at Garrettsville, OHs Nelson Ledges Quarry Park
