Perpetual Groove completes the Late Night Stage Throwdown Trifecta, joining The New Mastersounds and Big Gigantic, to keep the music moving until 3:00 a.m. each morning.

And that’s not all. More bands and special guests announcements are forthcoming.

We’re extremely pleased with the way the line-up evolved this year, says festival founder Ken Hays.  “Festivals are more popular than ever, and with this cutting edge lineup, we continue to reinvent ourselves, while keeping our core base engaged. It’s the best of both worlds. There’s something for everybody at the Vibes.”

Returning as Master of Ceremonies is Woodstock’s Wavy Gravy, in the midst of his 75th birthday celebration. Part of the birthday celebration includes a May 27th bash at New York’s Beacon Theatre, where Jackson Browne, Vibes artists Dr. John and Steve Kimock, Vibes alumni Bruce Hornsby and Jorma Kaukonen, and many others will star in a special concert to benefit the Seva Foundation.

Wavy Gravy will share the MC role this year with new partner and Vibes co-founder Bob Kennedy, in light of the recent loss of longtime co-MC Michael James Potashnick. This year’s festival is dedicated to his memory. Michael was family,  says Kennedy. "He exemplified what the Vibes means to so many...we will miss him greatly, and I have no doubt that on Thursday, July 21, his spirit will stand next to us on the stage to welcome the VibeTribe back to another amazing weekend of music and family."

Initially named ‘Deadhead Heaven,’ the festival continues to be an annual forum for fans across the country to remember the countercultural icon. Gathering of the Vibes combines legendary artists with emerging acts to appeal to a wide cross-section of live music enthusiasts. The festival creates wholly unique musical experiences for attendees far and wide. People come to the Vibes annually to build and renew their bonds of friendship, a community that has affectionately become known as the ‘VibeTribe.’
