2. There is also a CD intituled "Transcription in the light of harpsichord technique for the modern piano of the Chromatic fantasia of J.S. Bach, followed by a fugue and other piano music and transcriptions Kaikhosru Sorabji" performed by Michael Habermann. Bis, 2003
This CD contains several pieces :
Rapsodie espagnole / Maurice Ravel
transcription pour piano par Sorabji (1945).
Passeggiata Veneziana (1956).
Variation 56 (Variations for piano and orchestra, version for piano solo).
Quasi habanera.
Transcription in the light of harpsichord technique for the modern piano of the Chromatic Fantasia of J.S. Bach, followed by a fugue.
Pasticcio capricioso sopra op64 No1 dello Chopin
It looks interesting.
This is one of the few Sorabji recordings I don't have (yet), and I'm not sure if I will get it eventually, for the simple reason that I find Mr. Haberman's playing of Sorabji's music (I do have a number of CD's by him) not so very attractive. Quite possibly my fault, but so it is. Nontheless, you might want to try this CD (rather than go to Opus Clav right away), since the pieces presented are fairly short and simple.
3. There is a third CD : "Piano Sonata no 1" by Marc-André Hamelin, Altarus, 1990
Wonderful, get it! It's Sorabji's 2nd Sonata, but the first did not get a number (so now it's known as "No. 0"). It's an early work, fairly short and very expressive and, to Sorabji standards, fairly simple to follow.
You mention Jonathan Powell as a good interpreter of Sorabji's works.
Then you got me wrong, for I think he is a
superb interpreter of Sorabji's works! Lucky for us then that he has so far recorded more than any other peformer, and played even more!
Do you know Hamelin's recordings ?
A few, besides the Sorabji Sonata you mention I have him on a number of Alkan CD's and Rzewski. The Alkan are jawdropping...

Michael Habermann
Only on 3 Sorabji CD's (which are reprints of early Sorabji recordings, first issued on LP). He plays well but, as, said, to my taste they lack something. This dosn't mean they are bad, of course, my opinion says only something about
my opinion, not anything about the pianist!
A concerto for solo piano ? A piano symphony ? What the hell is that ?
A concerto for solo-piano is a work in which the piano plays both the solo-part as well as the "orchestra" part, meaning they are quite distinct. The earliest example is perhaps Bach's Italian Concerto (in which the "solo" and "orchestra" parts are further distinguished by way of different registrations on the harpsichord, somthing that can't be done on a piano, of course. Alkan's Concert for Solo Piano is another such solo-concerto.
A piano symphony is a work which has all the characteristics of a symphony (i.e. symphonic though, developements etc.), but played on a solo piano. Something like an organ symphony (Widor and Vierne are notable examples in this). To quote Sorabji (sort of), "a piece written
orchestrally for the
piano in terms of the
piano". If you play a Liszt piano-transcription of a Beethoven symphony, you have a symphony for piano. Now think of a similar piece, but written straight away for the piano.
Hope the above is a bit helpful to you!
