This June, Pennsylvania’s Ardmore Music Hall will once again host Unlimited Devotion: A Celebration of the Grateful Dead, a two-day fundraiser supporting the Rex Foundation and Camp Winnarainbow and honoring the latter’s founder, activist and entertainer Wavy Gravy, while celebrating his birthday.

The event will feature offerings from a slew of musicians, starting on Friday with sets from guitarist Tom Hamilton and Holly Bowling & Friends, The Wavy All Stars (John Kadlecik, ALO’s Dan Lebowitz, Reed Mathis, Jay Lane and vocalist Hayley Jane) and Matt Butler’s Everyone Orchestra (with Steve Kimock, Eric Krasno, Todd Stoops, Natalie Cressman, John Morgan Kimock, Cabinet’s Pappy Biondo, Robyn Sylvester and Hayley Jane).

Saturday’s music will include sets from Rooster Conspiracy (Krasno, Stoops, Mathis and Lane), Jeff Austin Band with special guests Biondo and Jane, The Gravy All Stars (Steve Kimock, Lebowitz, Sylvester, Austin, Cressman, Butler, JM Kimock and Biondo) and a late-night set from Dead tribute act Splintered Sunlight.

Unlimited Devotion will also include a Grateful Dead art exhibit, a brunch with music from Steve Kimock and a panel featuring a Q&A with Wavy Gravy and special guests.
