Jay Si Proof

Jay Si Proof is a musical collective playing earth jazz, founded in 2019 by trombonist/singer Jeff Chilton in Portland, OR. Playing between dancy grooves, catchy melodies, personal lyrics, and jazzy harmonies, Jay Si Proof's music strikes a balance between being thoughtfully arranged and passionately improvised. The band has been described as a cross between Steely Dan and Chick Corea fronted with vocals and horns. Jay Si Proof is a band with an intention. "We believe that when you listen, dance, or play music you are participating in whole being therapy which brings your body and mind into harmonic balance. We create new decade sounds rooted in funk, disco, jazz, afrobeat, and lofi hip hop traditions that are crafted and performed with purpose to elevate us all into a refreshing higher state. The proof is in the music!" -Jeff Chilton
