Although Phish is only a memory, group members Trey Anastasio and Mike Gordon have signed on for separate appearances at the fourth Bonnaroo festival, to be held June 10-12 in Manchester, Tenn. Anastasio and his solo band will perform what is billed as a "very special late night show" on a date to be announced, while Gordon will play a set with New York improvisational act the Benevento/Russo Duo.

Other newly confirmed additions to the Bonnaroo lineup are Mouse On Mars, Tea Leaf Green and the Old Crow Medicine Show. Organizers promise additional "major acts" to be added in the weeks ahead.

The Dave Matthews Band, Modest Mouse, Joss Stone, Toots and the Maytals, the Allman Brothers Band and Gov't Mule lead the list of previously announced performers for Bonnaroo, tickets for which go on-sale tomorrow (Jan. 29) via the event's official Web site.

This year's on-sale is a month earlier than the three previous years, which organizers say is a reaction to market conditions. "We felt this would be a year to get out there early," says Jonathan Mayers of promoter Superfly Presents.
