Which group has released two albums named after Marx Brothers films?

Queen released two albums in reference to the Marx Brothers, "A Night at the Opera" in 1975, and "A Day at the Races" in 1976.

'A Night at the Opera' is the fourth studio album by the British rock band Queen, released on 21 November 1975 by EMI Records in the United Kingdom and by Elektra Records in the United States. 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 of the same name, which the band watched one night at the studio complex when recording.

'A Day at the Races' is the fifth studio album by the British rock band Queen, released on 10 December 1976 by EMI Records in the United Kingdom and by Elektra Records in the United States. It was the band's first completely self-produced album, and the first not to feature producer Roy Thomas Baker. Recorded at Sarm East, The Manor and Wessex Studios in England, A Day at the Races was engineered by Mike Stone. The title of the album followed suit with its predecessor A Night at the Opera, taking its name from the subsequent film by the Marx Brothers.
