Amazing Solo Piano Recordings

Hagood Hardy, "Alone". Hard to find, but the catalog reference on the CD sleeve is Solitudes Ltd., 1131A Leslie Street, Suite 401, Toronto, Canada M3C 3L8
and the catalog/item # on the CD itself is SOLCD02. This is a remarkable recording, both musically and from an engineering standpoint. Not all the selections are purely solo piano, as a drum set and string bass are also used on some tracks. Also would recommend any of the Jim Chappell CDs. (My personal favorite is "Nightsongs and Lulabies".

On LP (can't vouch for the CD)...
Nojima Plays Liszt - Reference Recordings RR25
Nojima Play Ravel - Reference Recordings RR35
These are superbly engineered recordings of
phenomenal performances
Moravec: Piano Works fo Debussy and Ravel - Athena ALSY 10002 (remastering of same from Connosseur Society recording CS 2010)
Moravec - Chopin: Nocturnes - Connoisseur Society CS 1065

Almost any of the Connoisseur Society piano recordings will be excellent - extremely natural, well balanced sound, with a listening perspective on the piano that matches a true listener's perspective in a small performing hall. No raz-a-ma-taz, just exceptionally natural sound.

Valentina Lisitsa amazing! Can get them from amazon. Beautiful recordings, open sound,very dramatic. Try shostokovich first.

Bill Evans "Conversations With Myself," Verve 20 bit CD reissue # 314 521 409-2. Now if I can only find it on vinyl! Enjoy!

Rushton's suggestions are excellent. They sound excellent on CD as well (the Connoisseur Society ones have been issued by VAI, and are among the most natural recordings of a piano you'll ever hear on CD). In addition, the most spectacularly dynamic piano recording I've ever heard is an RCA Direct to Disc, 45 rpm recording of the Beethoven Appassionata played by a Japanese woman whose name escapes me. Ronc played that one for me when I visited him, and I've borrowed a copy since, but it's out of print and tough to find used and in good condition. I'm not giving up on it though. Worth looking for. If you have a good vinyl rig and play it, you'll wonder what everyone is thinking when they complain about vinyl's limited dynamic range! Finally, I'll note that piano sounds especially natural on SACD--no problems capturing dynamics and transient attacks, as is usually the case with vinyl (not on the ones mentioned above or by Rushton), or the harmonic correctness you thought you could only get from analog. The new Perriah Goldberg Variations on Sony SACD is a superb recording and an excellent performance, maybe not Glen Gould but then no humming either.
