Two up quarks and one down quark - that's a proton!
Anyways, I quite liked most aspects of the piece, some very cool dissonances, although I have to say I prefered Aries. I think there were a few to many sudden changes in mood and tempo in this one.
My main criticism I can make in the limited time I have at the moment is that the opening sounded a bit disjointed - especially with the slightly random long note in whatever instrument that was and the slightly out of place saxophone run.
Anyway, apart from the sudden changes in mood/tempo, the individual sections of the rest of the piece seemed to flow quite well within themselves.
I don't really have time to analyse all the specifics in form and development now so I think I'll just leave it at that. Generally quite well done!
