On December 4, 1992, Diana Ross took the stage of the Ritz Theatre in New York for a concert commemorating her appearance as Billie Holiday in the film biography 'Lady Sings the Blues', 20 years before. She was backed by an A-list of jazz musicians, and her set list consisted of jazz and pop standards from the 1920s, '30s, and '40s, most of them associated with Holiday. This "special, intimate evening of jazz and blues," as Ross put it, was devoted to "what jazz and blues is really about, which is loose and free and mellow."
