I've read a lot of these books on meta-music. They're interesting but not always applicable. If you don't know Victor Wooten, he was the bass player for Bela Fleck and also has some solid solo releases. I think if I didn't know how good Wooten was, I'd've dropped it. There's a lot of new-agey ideas that I wouldn't have even tried if I didn't trust him. I'll need to re-read but what I've learned so far has simplified improvisation and enjoyment.
