If you're a musician, you've no doubt been bitten by the harmonica. As a Chicagoan, we were blessed with our "favorite sons", Larry and Jerry Adler. Now Jerry is gone. Just as soul-searching as an violin,
the harmonica geniuses of the Adler clan did much to forwarded the acceptance of the harmonica as a beautiful, intensively personal voice in all aspects of legitimate and pop music. God Bless them all!

I know and have worked with two other harmonica monsters from Chicago: Corky Siegel and Howard Levy. Both brilliant.

You ain't kiddin!!
Of course, Toots Thielsman (also a jazz guitarist), probably has backed more artists/producers than anybody. He's great!!
And Stevie Wonder, who has written that Toots was his mentor...

I worked with Jerry, in Hawaii, many years ago at the military clubs. He was a wonderful person to work with. Sure had some long charts though. The "Grieg Concerto" was about ten pages long! Later, Ray
Thanks Mac. That was utterly fantastic!!!

That was a great link Mac. My first time to enjoy Toots as far as I know. I've probably heard him before, not knowing who I was listening to. While I was there I picked up another link from the list and I has to listen to it a couple of time before leaving. :>) I figured others might enjoy it also so here it is. Two great intertainers having to much fun.

I missed this one with Stevie's unannounced jam with Toots. Both great harmonica artists...both multi-instrumentalists!
I've added this and a few other videos (Bacharach) (Isley) in the downpage, amidst the Metheny videos.

Be careful about Peggy's reference in that second video.
Ben Franklin did not invent the harmonica.
Ben Franklin did, however, lay claim to the invention of the Glass Harmonium, a completely different instrument.
TV writers have always been rather shallow on the references, it seems.
Good performance of Toots, though.
