William Scott Bruford (born 17 May 1949) is an English retired drummer, composer, producer, record label owner and musicologist who first gained prominence as a founding member of the progressive rock band Yes. After his departure from Yes, Bruford spent the rest of the 1970s playing in King Crimson (1972-1974) and touring with Genesis (1976) and U.K. (1978). Eventually he formed his own group (Bruford), which was active from 1978-1980.

In the 1980s, Bruford returned to King Crimson for three years, collaborated with several artists, including Patrick Moraz and David Torn, and formed his own jazz band Earthworks in 1986. He then played with his former Yes bandmates in Anderson Bruford Wakeman Howe, which eventually led to a very brief second stint in Yes. Bruford played in King Crimson for his third (and final) tenure from 1994-1997, after which he continued with a new configuration of Earthworks.

On 1 January 2009, Bruford retired from public performance, barring one private gig in 2011. He released his autobiography, and continues to speak and write about music. He operates his record labels, Summerfold and Winterfold Records. In 2016, after four-and-a-half years of study, Bruford earned a PhD in Music at the University of Surrey, in the same year Rolling Stone magazine ranked Bruford No. 16 in its list of the “100 Greatest Drummers of All Time”. He was inducted into the Rock and Roll Hall of Fame as a member of Yes in 2017.
