I like improvisation, because
1. It is an insulting gesture to popular music and Jazz to parody it by pointing out its fundamental rules and showing its fundamental shallowness
2. It helps me, by parodying styles, to remind me of how formulaic most musics are, even in improvisation
3. The best way to avoid writer’s block is when you just do something. Writer’s block happens if you are thinking too much about something and don’t genuinely have any good thoughts on an issue. Acting on impulse always is the strongest conviction, but can be done well, or very badly.
