I was mightily impressed when I first downloaded this.
The whole piece gives me the impression of a stream of consciousness, what with the wonderfully relentless creativity. Top quality piano writing combined with lush orchestration, mixed with rich harmony!
I had to refrain from commenting immediately because there's simply so much to take in. I was worried I'd miss some important bits. Now, several listens in, I'm beginning to build up a clearer picture, but it's still sounding fresh, which is great.
Nothing else to add except a question: may I ask when you wrote this work (the original)?
