Sarah and Steve perform together, piano and voice, and with The Steve Alper Quartet/Quintet/Septet. They have appeared everywhere from retirement communities to large venues, primarily performing songs from the Great American Songbook, but also specialty and seasonal shows.

Sarah and Steve can be heard on the CD Sarah Knapp and The Steve Alper Quartet Present The Big Christmas Show and Ben Bagley's Harold Arlen and Vernon Duke Revisited, Vol. 2.
