Thanks, rv, for the Sofronitsky which I didn't know. Just had to try that bit from the Scriabin Fantasy myself, but can't get anywhere near the magic of it...
And thanks, ethure, for the Hisaishi: didn't think it would work for me, but it rather did after all.
Here, to make up for my unkind words about Hamelin in the original post, is the great man on top form in Medtner's Improvisation op. 31.1 from the Composer-Pianists album: maximum thrills at 4:07 min., nothing on his all-Medtner albums beats this, I think.
