It was about time to start on the jazz greats. The Duke is No. 1....please let me know your preferences. I'd go for Parker and Coltrane, Peterson possibly, Brubeck....but the list is so big, and it's so taste-governed I'm not sure where to start here. I'm certainly not an afficionado.
If you are interested in buying the Ellington embroidery in the background, it is $50 worth of work. I drew it and my wife Kay embroidered it. Let me know and we'll put it up on the site for you.
