By 1974, The Piano Choir had recorded two critically acclaimed albums, Handscapes (Strata-East SES-19730) and Handscapes 2 (Strata-East SES-19750). The first recording included original material and works by two legends of American music, Thelonius Monk (" Straight, No Chaser") and gospel composer Thomas A. Dorsey ("Precious Lord"). But, it was the second album in which Cowell introduced the synthesizer as a new instrument to jazz.

The Handscapes recordings, which are hard to find nowadays are now available on this site.
