What is the title of Queen's 1974 album featuring the song 'Killer Queen'?

The title of Queen’s 1974 album featuring “Killer Queen” is “Sheer Heart Attack.”

Released on 8 November 1974, Sheer Heart Attack was Queen’s third studio album and a major step toward the band’s classic sound. It was produced by Queen and Roy Thomas Baker, with recording taking place at several British studios, including Trident and Rockfield.

“Killer Queen,” written by Freddie Mercury, was the album’s first single. It became Queen’s first major international breakthrough, reaching number two in the UK and number 12 on the US Billboard Hot 100. The album itself was also Queen’s first to reach the US top 20.

A common mix-up is A Night at the Opera, the 1975 follow-up that contains “Bohemian Rhapsody.” Queen II came immediately before Sheer Heart Attack, while News of the World followed in 1977.
