Randy Singer posted a clip of of Sam Friedman playing diatonic jazz.
Remember Elvis? I maintain that Elvis would have happened without Elvis. The blues, R and B and Gospel were already popular and well developed musical styles. All we needed was an Elvis, a talented, good looking, white singer to bring it to white culture. It could have and would have been someone else if Elvis had not come along.
Remember the Beatles? Although they also studied these musical styles and it showed on the first couple of albums, suddenly they started putting out VERY original music. In my opinion you could not have had the Beatles without the Beatles.
I maintain overblows were in use at least since 1929. I maintain Theilemans, Turk and Scarlett used overblows in an advanced way as early as 1967 and there are probably many other examples I did not know about. Jazz was a popular and well defined musical style long before Levy began to play. In my metaphor, Levy is Elvis. We could have had Levy without Levy.
All due respect, he is a great player and what I am saying is conjecture. In harmonica history, Levy popularized overblows and no debate can take that away from him.
