Jay Russell Oliver (born April 26, 1959) is an American jazz musician (piano, keyboards and synths), composer, record producer, programmer and engineer.

His later credits include: Sheryl Crow, The Eagles, Jimmy Buffett, Wynonna Judd, Glenn Frey, Peabo Bryson, Chick Corea, Dave Weckl, Russ Kunkel, Jay Graydon, AO Music, Celine Dion and many others.

At the beginning of 2011, after many years of research and field test studies involving the use of sound from a clinical perspective, Oliver founded a company called SmartWav.

The company specializes in the use of proprietary tonal, pitch and rhythm mapping technologies that specifically aid infants in areas of brain development and issues of post-womb insomnia.

Oliver was a top local producer [citation needed] in his St. Louis studio when first introduced to a young Sheryl Crow, who at the time was a school teacher and aspiring singer.
