Few singers have possessed a baritone as rich and comforting as that of Bill Withers. Even smaller in number are the songwriters who have shared the West Virginian's natural ability to articulate a comprehensive range of emotions and perspectives -- jubilation and gratitude, jealousy, and spite -- with maximal levels of conviction and concision. Late to arrive, the everyman R&B paragon had just turned 33 when "Ain't No Sunshine," the unfading ballad off Just as I Am (1971), made him a sudden and unlikely success story, within one year an aircraft mechanic-turned-million-selling, Grammy-winning artist.
