As a guitarist and keyboardist, Miller released a recording of his own compositions, Singing Whale Songs in a Low Voice (on his Hip Pocket/Windham Hill Jazz imprint) which featured Isham and pianist Art Lande.
He also worked with many of the other Windham Hill artists, including label founder William Ackerman, Liz Story, Alex de Grassi, Darol Anger, Barbara Higbie, Scott Cossu, Nightnoise, Michael Manring and Andy Narell.
He and Ackerman developed a system of pressing records which enabled the label to domestically manufacture and sell audiophile quality LPs for standard LP retail price.
Singer-songwriters he has worked with include Richard Marx, Suzanne Vega, Dar Williams, John Gorka, Patty Griffin, David Broza, Paula Cole, and Glen Phillips.
Jazz artists include Manhattan Transfer, Michael Brecker, Medeski, Martin and Wood, Rick Braun, Bobby McFerrin, Paquito D’Rivera, and Dave Valentin.
