Anastasio, who recently received probation for felony drug charges in upstate New York, is scheduled to perform a one hour solo-acoustic set at the event, which will also feature separate sets from Phish members Jon Fishman (playing with the Yonder Mountain String Band) and Mike Gordon (playing solo).

"We've always wanted to have Trey perform at the inaugural Rothbury Festival," says Don Strasburg, VP/talent buyer for Rothbury promoter AEG Live Rocky Mountains. "It wasn't until two months ago until any possibility raised its head and only in the last two or three weeks did the possibility become a potential."

The presence of 3/4th of Phish is bound to raise further speculation about a reunion of the seminal jam band, which split for good in August 2004. The full band was on hand last month to accept a lifetime achievement award at the Jammys in New York, but did not perform together.

"Trey is part of our community's core family," Strasburg says. "And to have such an incredible musician and performer be willing to join us on an inaugural year makes a statement to the potential that Rothbury has."
