In 1981, he met Larry Pierce, a jazz keyboardist who had previously been a member of Blood, Sweat and Tears.

Together, they performed as 'Richard Hart & Swans Down featuring Larry Pierce' at the Susan Powell Fine Arts Auditorium in Elk City, Oklahoma.

He formed a quartet with jazz saxophonist Ron Munn, bassist Dorothy Soto, and percussionist Mark Winkel, and they recorded Fearless Shores in 2005, which was later released on the Schepora IRL label.

The quartet went on to perform at the Charlie Christian International Jazz Festival in Oklahoma City in June 2005.

Since 2009, Hart has continued to work with new musicians from Oklahoma, performing throughout the region including the Texas Panhandle.
