I have been informed this is not the first version: Hi - I listened to your clip, but it is actually the second of three versions (Rachmaninoff wrote one in 1926, 1928 and 1941 - the clip you have here is the 1928 one. I know because I played and studied all three versions.
I recently heard a recording of this version (1928) made in 1939 by a female pianist - a recording which was made before Rachmaninoff made his in 1941. I also heard another live performance recording from 1973 (once again the 1928 version). The only complete commercial recording was by Willaim Black and Igor Bouketoff in the 1990's. The reason I mention this is that there is still the original version before this one - from 1926.
Wow never heard that one but Istille prefer the 1926 version
