Well put.
I haven't many examples of Ronnie Beer's playing, though from what I can tell, I like him and would like to hear more.
Myself, I'd like to hear more of the SA contingent outside of the BOB scene, that is, players who ran on their own. Sadly, without much access to the music produced in SA during the '60s that didn't make it far outside the country, it may be damn well impossible to get a clear picture of other strains.
