His death was announced by his manager, Joe Gordon, who said that Mr. Jarreau had been hospitalized for exhaustion two weeks ago. On the advice of his doctors, he had canceled his tour dates and retired from touring.
Mr. Jarreau did not begin a full-time musical career until he was nearly 30, but within a few years he had begun attracting notice for a vocal style that was both instantly appealing and highly unusual.
Critics were particularly taken by his improvisational dexterity, in particular his virtuosic ability to produce an array of vocalizations ranging from delicious nonsense to clicks and growls to quasi-instrumental sounds. May his soul rest in peace.
