Thursday August 13 marks 40 years since the Grateful Dead took a night off from a lengthy hiatus to perform at the tiny Great American Music Hall in San Francisco in 1975. The concert showed off a batch of the new material the band had been working on and achieved legendary status when in 1991 a recording was issued as the first Grateful Dead archival release entitled One From The Vault. Great American Music Hall will celebrate the occasion by hosting a re-creation of the magical performance featuring a slew of Bay Area musicians.

This special evening will feature Mark Karan, Robin Sylvester, James Nash, Neil Hampton, David Gans, Totally Dead (Will McCosker – drums, Dave Gantenbein – bass, Ned Patchett – guitar & vocals, Matt Salata – guitar & vocals, Jaime Cintado – keys & vocals, Eileen Flynn Bell – vocals), Teja Gerken, Alex Bleeker (Real Estate), Jason Crosby (Doobie Decibel System), Kyle Field (Little Wings), Roger McNamee (Doobie Decibel System), Cochrane McMillan (Tea Leaf Green), Danny Eisenberg, Henry Kaiser with Bob Bralove, Scott Amendola & Michael Manring, Grahame Lesh, Harry Duncan plus many more special guests.

Show organizers have secured the backdrop used by the Grateful Dead on August 13, 1975 and it will be displayed behind the performers on Thursday. Tickets are on sale now via the venue’s website. A portion of ticket sales will benefit the Rex Foundation.
