[Brent Hahn]

You could try scat-singing a "guitar solo" into a recorder, and then learning to play what you sang.

Bob's article has this interesting bit - "I’ve also found that some songs seem to cry out for pre-arranged leads, while others demand raw improvisation. For example, the blues demand the latter: I find it uncomfortable to do pure blues without freshly improvising the solos."

Here's a blues -- well, a caucasian, suburban, Presbyterian attempt at a blues -- where I did the "raw improvisation" by singing the thing, and then sat down and learned to play it. In Edison terms, 20 seconds of inspiration followed by 20 minutes of perspiration. But then again, Bob's a very good player while I'm more of an... "editor."

The solo's at around 1:40.
