Q - I would, with respect, take issue with just one of your comments above - that Morton was thought of as a "blues, not jazz, artist". Paul Oliver - who I knew briefly in the '60s - wrote many solid books and articles on jazz and blues, but "Screening The Blues" is, IMHO, not gospel (pun intended).

A good, long listen to Morton's output on conventional labels and on the Library of Congress recordings demonstrates that, while Morton certainly had a grounding in blues, he also had a solid grounding in the classical repertoire and in ragtime, and made a major contribution to jazz. I've never personally thought of him as a blues musician - in spite of what Paul might have written.
