Bob Weir’s Ratdog, David Grisman, and Deep Banana Blackout make appearances at two increasingly popular summer “campout”-type festivals this year: Ekoostik Hookah-hosted Hookahville and the Grateful Dead-inspired Gathering Of The Vibes.

Hookahville takes over the Buckeye Lake Music Center in Hebron, Ohio, May 26 – 28 and features Arlo Guthrie in addition to Ratdog, the David Grisman Quintet and Deep Banana Blackout.

Ekoostic Hookah, a self-promoted Ohio jam-band favorite, has been staging the event Memorial Day weekends since 1994.

In the past, Ratdog, Jazz Mandolin Project, Merl Saunders And The Rainforest Band, Zero, The David Nelson Band, and Leftover Salmon – – among others – – have played the Hookahville stage.

If the Ohio camp-out isn’t enough for the traveling festival-follower, Gathering Of The Vibes June 23 – 24 at the Bridgeport, Conn., Seaside Park may satiate the crave for a Grateful Dead-type communal experience.

As per tradition, this year’s Gathering Of The Vibes camp-out falls on the weekend after summer solstice, and features an eclectic lineup of artists.

Ratdog, Grisman and Deep Banana Blackout follow up their Hookahville shows here, and other featured artists include jazz man John Scofield, funk masters Original P, moe., Strangefolk and Percy Hill.

Other confirmed artists are Walter “Wolfman” Washington and the Roadmasters, Merl Saunders And Friends, Soulive, Zen Tricksters, Tony Trischka, Sonia dada, Sector 9, Harlem Gospel Choir and Schleigho.

Bands will alternate on two separate stages, and there promises to be plenty of food, arts and crafts to go along with the music.

Of its fifth annual installment, Ken Hays of Terrapin Productions said, “Gathering of the Vibes started as a grassroots response to the death of Jerry Garcia, an attempt at keeping some of the Grateful Dead spirit and community alive.”
