I don't worry too much about the fundamentalist principles that are in almost any discussion about jazz.
There are musicians who go through their lives sort of shedding their skins. For me, I've always felt backward-compatible to Version 1.0.
There are some musicians who are talented and see themselves as some kind of natural geniuses or something because of a certain amount of natural ability. But that is often rarely the case over the long term.
From 1962 to 1965, the guitar became this icon of youth culture, thanks mostly to the Beatles.
I think jazz is actually quite unforgiving in its disdain for nostalgia. It demands creativity and change at its highest level.
I don't know if I would qualify as mainstream. I think I have managed to function pretty successfully on the fringes of the music world and have been able to play exactly what I have wanted the way I have wanted.
