Charlie,
I'm listening to the Chamber Orch. piece, and it sounds great! I didn't know Dominic conducted (he's played some of my percussion music). I'm guessing you're into the whole Spectral school - some of the opening passages of that reminded me of Grisey, in a good way, of course! I was wondering what the instrumentation was - but now I see it in your last post. Some of the sonorities sounded electronic - I thought it was perhaps an accordion. Now I'm guessing it was organ! I'd like to see the score.
I haven't listened to the Triangle piece yet. But, of course, I immediately think of Lucier's piece for solo triangle - Silver Streetcar for the Orchestra....
