Thanks for listening in such detail Andrew, I'm pleased some parts take your fancy. I rarely improvise to imitate anybody past or present and I constantly try to expand my aesthetic using the spontaneous and the transient, you're certainly right about that. Transience and permanence are rather deeply tangled properties for me, with some features moving from one state to the other over time. I did amass quite a heap of written compositions in earlier years, a few of which I have posted here but with age I felt them to be too derivative and wanted something different. One certain thing about improvising is that we must be completely ourselves. We can assimilate as many features and techniques from as much music as we like but we absorb them, they ought never to absorb us. Almost all improvisation tutorials seem to assume the opposite premise which extrapolated to its conclusion really would have everybody playing the same way, a result which, I agree with you, would be bad for us and bad for music.
