Harry Edward Nilsson III (June 15, 1941 – January 15, 1994), usually credited as Nilsson, was an American singer-songwriter who achieved the peak of his commercial success in the early 1970s. His work is characterized by pioneering overdub experiments, returns to the Great American Songbook, and fusions of Caribbean sounds.
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. 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.
His honors include Grammy Awards for two of his recordings; Best Contemporary Vocal Performance, Male in 1970 for "Everybody's Talkin'", a prominent song in the 1969 film Midnight Cowboy, and Best Pop Vocal Performance, Male in 1973 for "Without You". In 2015, he was voted No. 62 in Rolling Stone's list of "The 100 Greatest Songwriters of All Time".
