Widespread Panic, John Fogerty, moe. and Umphrey’s McGee are among the acts slated to appear at the 2014 Gathering of the Vibes. The veteran summer music festival will return to Bridgeport, CT’s Seaside Park from July 31-August 3. In an unexpected turn of events, the Disco Biscuits will play a special set with Grateful Dead drummers Mickey Hart and Bill Kreutzmann. The festival announced its lineup during the Kung Fu and Deep Banana Blackout show at Port Chester, NY’s Capitol Theatre last night.

This year’s festivities will boast both Widespread Panic and John Fogerty’s first performances at Gathering of the Vibes. Since Fogerty performed with Panic at the inaugural Lockn’ Festival this past September, some collaboration seems possible. The Disco Biscuits—who announced earlier this week that their annual Camp Bisco festival will take a hiatus this summer—have not performed at Vibes since 2001. This is the first time since 2004 that neither Bob Weir nor Phil Lesh is on the festival’s lineup. However, in addition to Hart and Kreutzmann’s set with the Disco Biscuits, Vibes will maintain its focus on Grateful Dead-related projects through performances by Dark Star Orchestra. Joe Russo’s Almost Dead and Keller Williams Grateful Grass.

Other acts of note include: Edward Sharpe and the Magnetic Zeros, White Denim, Maceo Parker, Slightly Stoopid, Dumpstaphunk, Rodrigo y Gabriela, Leftover Salmon featuring Little Feat’s Bill Payne, Ryan Montbleau & Friends, Kung Fu and American Babies, among others. EOTO, Deep Banana Blackout, Dopapod and Digital Tape Machine will perform “late night ranger sets.” Wavy Gravy will serve as the event’s MC.

Tickets are available now on GOTV’s website. Check out the full lineup below.
