A Night at the Opera is the fourth studio album by the British rock band
Queen, released in November 1975. Co-produced by
Roy Thomas Baker and Queen, it was the most expensive album ever recorded at the time of its release. The album takes its name from the
Marx Brothers film A Night at the Opera, which the band watched one night at the studio complex when recording. The album was originally released by
EMI in the United Kingdom, where it topped the
UK Albums Chart for four non-consecutive weeks, and
Elektra Records in the United States, where it peaked at No. 4 on the
Billboard 200 and became the band's first platinum selling album in the US. The worldwide sales for the album are currently over 6 million copies.
