Ivan Neville’s Dumpstaphunk and the Jennifer Hartswick Band will co-headline a Phish after party on New Year’s Eve. The late night show will take place at New York’s Stage 48 shortly after Phish’s show at Madison Square Garden wraps-up a few blocks away. Both groups feature Trey Anastasio collaborators: both Hartswick and JHB trombonist Natalie Cressman perform in Anastasio’s solo band, while Dumpstaphunk’s Tony Hall played bass with Trey Anastasio Band from 2005-07 and performed with the Phish guitarist in Dave Matthews & Friends.

The evening will feature numerous collaborations. Dumpstaphunk will also showcase new material from their forthcoming album, Dirty Word.
