Jay Si Proof, or JSP, is the philosophical indie funk vision of multi-instrumentalist composer/arranger Jeff Chilton (Jay Si) whose credits include performing with The Diamonds, The Platters, Broken Social Scene, and recording on over 20 albums by Portland based ensembles. Described as "earth jazz alchemists" by Vortex Magazine, JSP was born in 2019 from the soggy jazz soaked earth of Portland, OR. Since its inception, the band has evolved through adventurous jazz fusion to low-fi jams to a full fledged funk party, all while prioritizing genuine messages of spirituality and human betterment in the midst of endless modern crises. Jay Si is joined by Lucas James (drums and vocals) JD Erickson (sax and flute), and Corey Heppner (guitar).
