Jay Si Proof

Jay Si Proof is an explosion of funk with unhinged, audacious, and joyous energy! There are no walls between performer and audience at a Jay Si Proof show, there are no boundaries between acquaintances, friends and strangers. Teetering between funk anthems, entirely improvised disco bangers, and sentimental lo-fi grooves, Jay Si Proof is as much an experience as it is a concert.

Eight long years ago, at the bright eyed and naive age of 22, Jeff Chilton road an Amtrak train from Ithaca, NY to Portland, OR with naught but a trombone at his side, an acoustic guitar on his back and a dream in his heart: to figure out the FUNK of it! The soggy jazz soaked dirt of Portland proved creatively fertile and after meeting fellow dreamers Corey Heppner, Lucas James, and JD Erickson, Chilton took on the moniker Jay Si and created the musical organism Jay Si Proof.

Since then, this entity has burst onto the music scene bringing its “silly and euphoric vibe” (Portland Mercury) up and down the west coast. With a voracious appetite for good times, Jay Si Proof cooks up the funkiest dishes where ever it goes. Described as "earth jazz alchemists" by Vortex Magazine, Jay Si Proof has been featured twice on PDX Pop Now, ranked in the Mercury's top music videos of 2024, and performed at countless PNW music festivals. Every performance is explosive with horn battles, crowd inspired fully made up songs, and blissful uplifting lyrics. Come enjoy the show and see for yourself that the PROOF is in the music!
