Back for their 19th year, Gathering Of The Vibes is set for July 31st – August 3rd at Bridgeport, CT’s Seaside Park.

The initial lineup announcement was revealed earlier today with a few big surprises including Widespread Panic in the headliner spot and members of the Grateful Dead joining trance-fusion jammers The Disco Biscuits for a set. See the full lineup below!

Vibes 2014 marks the festival’s tenth return to Seaside Park, making this location home to the Vibes more than any other venue. Cradling the Connecticut shore of Long Island Sound, Seaside Park boasts 370 acres of waterfront adventure that honors the legacy of legendary showman PT Barnum.

Tickets are available here.
