This tenor saxophonist is credited with authoring some musical styles that have anchored jazz for decades. During his relaxed but inventive solos with Count Basie's early big band, Young helped establish jazz's sense of cool—the flowing legato lines and dramatic rhythmic expressions in his 1939 solo for “Oh, Lady Be Good” opened up a whole world of swinging possibilities. He later adapted to bop's tempos with poise on tracks like “Ad Lib Blues”, and the way he set up Billie Holiday on “This Year's Kisses” raised the art of sax-and-vocal interplay to new romantic heights.
