An extravagantly gifted composer, arranger and pianist -- some considered him a genius -- Billy Strayhorn toiled throughout most of his maturity in the gaudy shadow of his employer, collaborator and friend, Duke Ellington. Only in the last decade has Strayhorn's profile been lifted to a level approaching that of Ellington, where diligent searching of the Strayhorn archives (mainly by David Hajdu, author of the excellent Strayhorn bio Lush Life) revealed that Strayhorn's contribution to the Ellington legacy was far more extensive and complex than once thought.
