Jay Si Proof was created by trombonist and vocalist Jeff Chilton 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, Jay Si Proof's original music plays between rhythmic grooves, personal lyrics, and jazzy harmonies, blending the finesse of a Steely Dan record with the aesthetic of old school funk like The Meters and new school R&B like Erykah Badu. Their music has been featured on Portland's KMHD radio and abroad in European and South American new music playlists.
