I'm sure many here are already aware of this but perhaps many are not. Some new recordings of Rachmaninoff playing have recently been unearthed. One is him playing snippets of his Symphonic Dances. Fascinating to listen to and until about a year ago never heard in public since his death. Hope you enjoy it as much as I did:
