Phish drummer Jon Fishman will join up with the likes of Oteil Burbridge, Natalie Cressman and Kung Fu on April 18 at The Hall at MP in Brooklyn as a benefit to Presidential candidate Bernie Sanders.

Fishman has long been supportive of Sanders, even setting up a Twitter account solely to promote the Vermont senator. The Phish drummer also helped introduce Sanders at an event in Portland, ME.

Admission to the event is free with a suggested donation of $27 to match the average contribution from each individual.
