San Rafael, CA’s Terrapin Crossroads has announced it will host a Labor Day Party this Monday, September 5, featuring live music including sit ins from venue proprietor Phil Lesh.

Performing at the event will be the Terrapin Family Band and Cosmic Twang, along with select collaborations with Lesh. The backyard party is free to the public and will feature games, food and drinks.

Lesh just finished up a weekend at Lockn’ Festival in which he played two main-stage sets that featured members of Phish, Joe Russo, Anders Osborne, the Infamous Stringdusters, Chris Robinson Brotherhood, Gary Clark and more, along with a VIP set that saw Lesh collaborate with fellow bassists Mike Gordon and Dave Schools.
