Zenph premiered the Gould "reperformance" on a specially prepared Yamaha Disklavier last September in Toronto; the next release will be of Art Tatum, along with other recordings from Sony BMG Masterworks' archives.

While producers usually want to touch up mistakes, "reperformance" recordings replicate the original musician's glitches, as well as his/her touch, timing, pedal actions and articulation — all with vastly improved sound, in the case of recorded performances from earlier days. And, as happened in New York (and in Raleigh two years ago), a legendary old performance can be recreated live on a piano for a new audience in the same room.

Each "reperformance" recording takes about five months to produce.
