Somewhere, I think at Wallach's Music City, I found a collection of Jelly Roll Morton tunes. Everybody I know was already singing "Hesitation Blues" onstage so I opted for his instrumental record and I also was getting a little tired of hearing just guitars everywhere. My favorite was the way he could run up the keys on "Darktown Strutter's Ball". He makes it seem so effortless.
(In this little sample, during a glide, do you hear the opening melody for "Oh You Beautiful Doll"? A song written in 1911? That's the kind of stuff the UCLA ethnomusicology department was absolutely made of)
