Les Claypool, Bruce Hornsby, and Deep Banana Blackout are among the first 13 bands announced by festival organizers, with more to sign up for the June 29 – July 1 music lineup.

As usual, the festival brings together established jam-band favorites as well as up-and-coming acts from across the musical spectrum.

Jazz great John Scofield, African drum pioneer Baba Olatunji and “Mardi Gras Indian” group Wild Magnolias join old favorites like Merl Saunders and his Funky Friends, Strangefolk, and Lake Trout on the Gathering’s stages. Soulive, Max Creek, Joules Graves, and Sloan Wainwright have also signed on to perform.

In addition to the music, there will be a full range of arts and crafts vendors, food and microbrews all three days. There is also a Kids Corner, and the Terrapin CyberTent where festival-goers can surf the web and check their e-mail.

Gathering of the Vibes is the first stop in the Terrapin 2001 series, which includes Camp Creek and The Summit festivals.

Advance tickets go on sale April 9 by phone, and are also available online at the event’s Web site. “Early Bird” tickets purchased the first week are $60 for a three-day pass, $55 for two days and $30 per single day – half the price of tickets at the gate.
