Alan,
A thoroughly interesting listen. I've experimented in the past with a more atonal approach to composing and listened to a lot of stuff i simply couldn't connect with.
I found your musically intelligent use of percussion illuminating, in particular the seldom used but great sounding soft mallet xylophone. The tonal structure of the theme at the start was interesting too, and i sense you've resisted the urge to go radically or mildly atonal, and found a balance i enjoyed a great deal.
And importantly, this type of music can sound completely meaningless, and IMO you've cleverly and intelligently avoided this trap, with careful repetition and variation, and not wandered off onto another musical planet non of us have ever been to. The orchestration is superb, and in the process of listening, i cast my mind to alternatives and could find few, even given the infinite possibilities the theme offers.
My only comment is with sound. The strings sounded at times too sweet, and i wonder if the aural picture would benefit from a slightly more raw sound, with more attack in selected passages. Where the clarinet comes in before the xylophone (about two thirds of the way through), and just before that again, i wonder if the attack in particular could be strengthened to contrast the W/W and mallet percussion. And going on from there, when the orchestration thickens a little, and you introduce the tenor (alto?) string line, if a 'rougher' sound would lift this further without adding anything else, or fiddling with the dynamics.
I enjoyed this, and my compliments and respects to you on a work, that in my opinion, has musical class, and provides a refreshing and musically intelligent alternative to the modern days perpetual river of 'epic dirges'.
Regards,
Alex.
