My friend Dan referred me to Ghostly Grand Piano: Technical Marvel Plays Like an Old Pro - washingtonpost.com, which in turn led me to Zenph Studios - Glenn Gould’s - Bach Goldberg Variations - Connections Column - New York Times:

Zenph also announced it had accomplished this feat
of technological legerdemain with one of the most remarkable recordings
of the last century: Glenn Gould’s 1955 mono rendition of Bach’s
“Goldberg” Variations. Gould, who retreated from performance into the
private realm of the recording studio where he could splice and fiddle
with sound and phrase, would be posthumously pulled back into the realm
of public performance.

I'm almost ready to plunk down the money to hear the recreation of Gould's famous Bach recording. (See *BACH:
The Goldberg Variations - Glenn Gould's 1955 performance re-created in
modern hi-res surround sound and hi-res binaural sound by Zenph - Sony
Classical for the album cover.) Where can I buy it?
