Jon Fishman will join headliners Adam Gardner of Guster and Pete Kilpatrick Band for Bernie Sanders’ Fight the Oligarchy Tour during its stop in Portland, Maine’s Brick South at Thompson’s Point. 

According to the event’s latest dispatch, music will start at 5 p.m. local time, with local indie rock group Weakened Friends taking the opening slot before Adam Gardner of Guster, who will be joined by Jon Fishman and Pete Kilpatrick Band. 

Notably, Phish’s timekeeper actively supported Sanders during the politician’s 2016 and 2020 bids for office, and even served as a co-chair for Sanders’ 2020 Maine Super Tuesday campaign and performed at a Sanders rally in Essex Junction, Vermont, with fellow Phish bandmate Mike Gordon.
