He made an interesting comment on soloing. B.B. King has said much the same thing:
“Oh, I’m in the moment when soloing. Practicing a solo ahead of time puts you in a position of being unable to reach it later. I don’t subscribe to that theory or that way of doing a solo. My solos have got to come straight out of me at the moment I’m doing them.”
Jo Bonamassa recently said the same sort of thing - his rehearsals now consist of checking the levels with the band and then leaving it alone, as practising stuff beforehand made him play in a way that was too mechanical.
