glad you like it! these days, i include something of medtner on every program. partyl to increase my own repertoire of his music (now I play 16 pieces of his) but also so people will eventually get used to it.
you see a lot of his music these days in europe, but less in the states, though the tide is turning ever so slowly. i think he is a great addition to the sort of viennese-germanic traditions, esp. for those who don't want to play atonal music like schoenberg or webern (which i happen to love!)
also medtner is surprisingly versatile when it comes to programming his music, you can put him next to bach, mozart, haydn, beethoven, schumann, brahms, grieg, or liszt, rachmaninoff, scriabin, etc. i think it's great and everyone should play something!
