When I was doing my last round of piano shopping and was looking for information about my Bluthner, I came across a story about Rachmaninoff - turns out he also owned a Bluthner (a grand piano of course), and he said that when he left Russia he only took two things with him: his beloved wife and his beloved Bluthner. This story made me like him even more, although I always liked his works, even if I'd be hard pressed to say which piece I would put in my top ten. The two "obligatory" preludes that I am studying for many years are probably among my favorites of what I know of Rachmaninoff's legacy (with the possible exception of his Paganini variations, although they aren't just for piano; I generally like variations as a music form, I think they are like life which can turn out this way or that but the theme is still recognizable). I was very impressed to learn that the first of these preludes (known in the West as the Bells of Moscow) he wrote when he was 14 years old...
Here James Rhodes plays the C sharp major prelude, and here's the G minor one by Kissin, and to hear my rendition you'll have to wait a bit more.
