It doesn’t take Sherlock Holmes to clue us in on who is the Queen of Jazz. It’s Ella Fitzgerald, my dear Watson, Lady Ella. William Basie began to boogie-woogie piano keys at a Harlem club catering to “uptown celebrities.” After a quick stomp through Kansas City, he came back as Count Basie. There are few true royalties among jazz, ask anyone waiting for residual checks, but as Duke Ellington made clear, these two had that thing which made them swing. Eagle Rock Entertainment is dropping two documentaries celebrating these American jazz icons: Ella Fitzgerald: Just One Of Those Things and Count Basie: Through His Own Eyes exclusively on digital formats on Sept. 11.
