Jon Anderson is an English singer, songwriter, and musician who co-founded the progressive rock band Yes with bassist Chris Squire in 1968 and rose to prominence as their lead vocalist. The band pioneered progressive rock in the 1970s, particularly with their critically-acclaimed albums The Yes Album, Fragile and Close to the Edge (1972) which display Anderson's role in crafting the group's sound as one of the main songwriters and lyricists. Known for his countertenor vocal style, Anderson was a member of Yes across three tenures until 2004.
