Last night in Philadelphia, Jazz Is PHSH brought their reinvention of Phish jams to World Cafe Live. During an unexpected “audience participation” portion of the night, brothers Matt and Adam Chase invited a guest from audience to join the band on stage. Asking the randomly-selected human from the audience to vocalize the trombone portion of The Story of the Ghost‘s “Meat”, it became clear that the forthcoming collaboration was pre-meditated as the “fan” stepped on stage and introduced himself as “Tom”. It was, in fact, Tom Marshall, the primary external lyricist for Phish known for his work on over 95 original songs–including “Meat”. Marshall sang the lyrics to his own “Meat” before departing and letting the band rip into the song toward the end of their set.PREMIERE: Cal Kehoe Shares Video For Soothing Single “Marilyn” Featuring Phish Lyricist Tom MarshallWatch Tom Marshall sing “Meat” with Jazz Is PHSH below:On Saturday, December 30, Jazz Is PHSH will perform a Phish pre-party at The Cutting Room with Natalie Cressman (Trey Anastasio Band), Chris Bullock (Snarky Puppy), Felix Pastorius (The Mu’tet), Jamar Woods (The Fritz), Adam Chase (James Brown Dance Party), and Matthew Chase (The Chase Brothers).
