NEW YORK — Peter Banks, one of the founders of the popular British rock band Yes, died March 7 at his home in London.
The cause, at age 65, was heart failure, according to the website of Flash, the band he formed after leaving Yes in the early 1970s.
Mr. Banks, a guitarist influenced as much by jazz as by rock, formed Yes in 1968 with bassist Chris Squire, singer Jon Anderson, keyboardist Tony Kaye, and drummer Bill Bruford. The band’s name was Mr. Banks’s idea.
Yes was one of the first and most successful purveyors of what came to be called prog (short for progressive) rock, with complex melody lines and unusual time signatures that required virtuosity to master.
Its best-known songs — all recorded after Mr. Banks left — include ‘‘Roundabout’’ and ‘‘Owner of a Lonely Heart,’’ a No. 1 hit in 1983.
Mr. Banks played on the band’s first two albums, ‘‘Yes’’ and ‘‘Time and a Word,’’ before leaving to form Flash. He was replaced by Steve Howe.
