...I've just heard a "monster" blues player, who shall remain nameless, but knew every "lick" known to man ... and used them all in 12 bars

I may not buy all the academia you mention, linguistic / metrics for instance, but it's a good reference to have. ... I'm not a purist, by any stretch. I was also surprised to hear Clapton describe the solo in Crossroads as wrong -lol- I guess he was a bit more the purist at the time

Anyway, just felt like saying GREAT JOB !
..now I'll go work on Old Love

-best,
Mike
