First off, I’d like to say you’re definitely the best improviser here and I always like to listen to what you come up with.
1. I don’t really see a resemblance in this to Boulez or Stockhausen, though some of the densest sections in it (1:38-1:47, 5:06-5:18, 6:04-6:10) definitely sounds like early Finnissy. They remind me of the clouds from English Country Tunes, particularly “Midsummer Morn”. Sounds sorta like smashing on random keys though; not your most inventive stuff.
2. This reminds me a lot of Xenakis’ Evryali: sort of like Evryali’s little brother. The Gestalt Periods, broken progressions and dense chords are very Xenakis-esque. I like the use of color in this, but I didn’t really feel like it developed. Sort of like once you’ve heard the first minute you’ve heard it all.
3. Meh. Way to strict with dynamics and rhythm. Least favorite of the set.
4. I really liked four. I thought it was definitely the best of the set. I would randomly learn this if it was a piece =P At first it sounded almost exactly like a piece by Finnissy called Folklore (start-0:45). Did I hear scales from the Mozart-Liszt Reminiscences de Don Juan (4:53-5:03)? Sounds like some of the Rachmaninov Piano Concerto No. 3 made it into there as well (2:45-3:10)? And the Glass Violin Concerto (3:10-3:22)? Ondine (3:30-3:33)? Also I think I caught some Castlevania in there at various parts XD
As a whole it reminds me a LOT of late Sorabji. Anyways, this was really incredible.
5. Second favorite. Very driving and didn’t get dull. Some of the chord progressions were very original; I don’t think I’ve ever heard them anywhere else.
