Philip Chapman Lesh is an American musician and a founding member of the Grateful Dead, with whom he played bass guitar throughout their 30-year career.
After the band's disbanding in 1995, Lesh continued the tradition of Grateful Dead family music with side project Phil Lesh and Friends, which paid homage to the Dead's music by playing their repertoire, as well songs of the members of his own group. Lesh operated a music venue called Terrapin Crossroads. From 2009 to 2014, he performed in Furthur alongside former Grateful Dead bandmate Bob Weir. He scaled back his touring regimen in 2014 but continues to perform with the Lesh family band, Phil, Cory, Heidi and Joseph Lesh.
