This is one strange piece of music, first composed in 1936. Compelling, however, and also strange to think that a Swing-era big-band leader chose this for his theme song. Downloadable for free at this link, or just play it there until you tire of it. If you do. I didn’t so I bought it at Amazon for 99 cents.
Clarinetist Artie Shaw was the band leader, a nice Jewish boy who had a few other quirks. Which I am discovering in this exceptional biography. Married eight times. Estranged from two kids—though one of them made an effort to forgive Artie in his old age. Not a model in the parenting or husband department, obviously, but a helluva musician who lived to age 94, and was gutsy to boot.
Shaw, already famous and wealthy, did WW2 as a Navy chief leading a Swing band for the forces at front-line places like Guadalcanal where he was once bracketed by dropped Japanese bombs and went deaf in one ear. The word picture I can’t forget is from 1943: his band playing Nightmare as they descended on an aircraft elevator to their below decks audience on the aircraft carrier Saratoga.
THE TEXAS SCRIBBLER 
The piece itself isn’t too original, in my humble opinion. The lead (is it clarinet?) is impressive and haunting, though.
It was original in 1936. Nothing like it, then. And, yes, that’s Shaw’s clarinet.
(I put both the date and the instrument in the post, when I realized I’d left them out.)
