while i wouldn't necessarily pick manifold curiosity as a whole to represent your 'pushing compositional barriers' strengths (as far as staying away from rock tendencies, i mean), the midsection (7:00-10:00) is really cool i think as far as the arrangements go (in terms of chord/note choices). the antique would be interesting, but as far as the longer 5-minute beginning goes, i wouldn't want them to skip through some of it and say 'Eh, this is all the same' and just disregard it- you know?
i think Marathon is a good choice, in that it's definitely compositionally interesting: rhythmically, in that it does not often fit easily into a predictable, head-nodding pattern; timbrally, in that the arrangement incorporates a lot of different instruments other pieces don't necessarily include (trombone, french horn, flute, organ, rhodes, etc.); emotionally, in that the peaks and low points of energy of the piece pretty much run the gamut; tonically in that its chordal progressions are interesting; production- and mixing-wise, especially with the drums at the end and the noises and voices throughout the piece. plus that whole rhodes end with the spoken word is just- GAH.
yeah. marathon. that be my thinking.
how is this to be submitted- in audio format, or in a written score?
