Yesterday, we reported on a Bernie Sanders campaign event featuring Phish drummer Jon Fishman, scheduled to take place tonight in Philadelphia, PA. Today we’ve learned some more information about the event, as Fishman will play with some all-stars from the Philly jam scene to help rock the vote.

At North Bowl tonight, Fishman will perform with a number of special guests, including Eli Winderman (Dopapod), Joe Baldacci (Muscle Tough), Ross Bellenoit (Muscle Tough), Jon Coleman (Muscle Tough), Clay Parnell (Particle), and Ian McGuire (CIA). There will also by support from local DJ Risky Disko. The festivities are set to run from 9pm to midnight, with the Sanders website calling this “a voter registration drive like you’ve never seen.”

The deadline to register for voting in the Pennsylvania primary is tonight, which would explain the strong showing from Fishman in the state’s major city. Get out and vote!
