Terrapin Crossroads has announced that it will host a full day of music on April 17 to celebrate the opening of its new outdoor performance space, featuring a special version of Phil Lesh & Friends.

Lesh will be joined by Eric Krasno, Neal Evans and Alan Evans of Soulive, along with Jason Crosby, the Terrapin Horns and a “very special guest,” for two sets on the day. Soulive and Scott Law & Ross James’ Cosmic Twang are also slated to perform during the event.
