Jazz is the seventh studio album by British rock band Queen, released on 10 November 1978. Roy Thomas Baker temporarily reunited with the band and became their producer; it was three years since he co-produced their 1975 album A Night at the Opera, but this album also was the last he co-produced for the band. The album's varying musical styles were alternately praised and criticised. It reached #2 in the UK Albums Chart and #6 on the US Billboard 200. Jazz has sold over 5 million copies to date.
