Fantastic, this is a great start, but it appears to me there is little depth to our knowledge and that my narrow question is getting a little squashed. I do appreciate, as context, what you have to say about 20th C. music from Asian composers, among which Takemitsu towers in popularity, only rivaled by Tan Dun, whom certainly is active currently.
But the narrow question is about worthwhile piano works. I am interested in titles, descriptions and analyses, how to get, recordings, websites promoting the disemination of this music, etc.
For those of you interested, this is an opportunity to raise the level of musicological knowledge in pianostreet and to explore this potentially very interesting area.
