The fame and influence of Chicago soul singer, songwriter, producer, and arranger Donny Hathaway seems to have grown exponentially since his suicide in 1979 at age 33. He only made three solo albums in his brief career, all between 1970 and ’73 (he did most of his work behind the scenes, for other people), but that music was far ahead of its time and remains incredibly powerful. His gospel-jazz vocal style opened the way for Luther Vandross and a million subsequent slow-jam singers, though most of them have never approached his outsize talent, artistic discipline, or good taste.
