Jeff Holdsworth is a musician who was a founding member of the rock band Phish. Founded at the Redstone campus dormitories of the University of Vermont (UVM) in the fall of 1983, the band originally featured Holdsworth and Trey Anastasio sharing lead vocal and guitar duties, Jon Fishman on drums, and Mike Gordon on bass guitar. Holdsworth left the band in 1986 after graduating from UVM to pursue a career in electrical engineering, shortly before the band recorded their debut self-produced album, The White Tape, though he had played on some of the demo recordings that would later be re-recorded for that album. His songs "Possum" and "Camel Walk" continue to be Phish live show favorites.
