Thanks furtwaengler for your appreciation. I don't come across many people who appreciate a more "far out" style of improvisation. I also improvise with the basic chord, scales and tool progression of "normal" sounding music, but I find I can't "space out" enough

I use improvisation as a form of meditation where the mind doesn't have to worry about what the right note to press is, just play without thought and get pulled by the sound.
I am facinated by how versatile the piano can sound, when I first hear Cowell's "The Banshee" I couldn't tell which instrument was being played! I didn't know a piano could sound like a woodwind almost! There are certainly ways to touch the strings on the inside that we haven't developed, but I don't think it is interesting for a mainstream audience. Afterall our musical journey is more for ourself that others isn't it?
When I play piano I pretty much play in 4 different styles. Almost a change of technique and personality at the keyboard. Classical, Jazz (cocktail, blues, ragtime etc), Improvisation (Classical,Jazz and misc style), Other (messing with insides of the piano, prepaired piano and whatever strange ways to use and abuse the piano

).
I do see the styles effecting and creeping into each others domain. For instance, when I play with the insides of the piano for a long while then go back to normal playing, I tend to hear the piano more as a wind instrument, although one strikes the note in a percussive fashion you can almost imagine that the sound coming out is coming from a breath or singing voice. Also I find that in mindless improvisations I catch myself playing shapes and patterns of normal classical music that I recently have been studying. So although I like to think them as seperate they do blend into each other but personally it enhances my experience rather than hinders it.
Thanks a lot for introducing me to Thomas Ades I will get a listen of his music.
