Matt Butler will lead his Everyone Orchestra in a Phish after-party on December 30, gathering a number of special guests for a Grateful Dead-themed “Everyone’s Dead” show in New York City during Phish’s New Year’s Eve run at Madison Square Garden.

Joining Butler will be Steve Kimock, Joe Russo’s Almost Dead’s Tom Hamilton, Holly Bowling, moe.‘s Chuck Garvey and Vinnie Amico, Snarky Puppy’s Mike Maher and Jeff Mosier of Aquarium Rescue Unit, with more guests to be announced. The collective will play one set in which they will “deconstruct” the music of the Grateful Dead, along with a traditional improvised Everyone Orchestra set, conducted by Butler.

Limited pre-sale tickets for the show, which will take place at NYC’s Gramercy Theatre, are now available to CEG Presents and Nolafunk email subscribers only. General ticket sales begin this Friday, November 17, at noon EST.
