Harry Edward Nilsson III, usually credited as Nilsson, was an American singer-songwriter who achieved the peak of his commercial success in the early 1970s. He is known for the charting singles "Everybody's Talkin'" (1969), "Without You" (1971), and "Coconut" (1972). Nilsson also wrote the song "One" (1968), made famous by the rock band Three Dog Night. A tenor with a three-and-a-half octave range, Nilsson was one of the few major pop-rock recording artists of his era to achieve significant commercial success without ever performing major public concerts or undertaking regular tours. His work is characterized by pioneering overdub experiments, returns to the Great American Songbook, and fusions of Caribbean sounds.
