Queen and David Bowie released the song "Under Pressure" in 1981.
The song was recorded at Mountain Studios in Montreux, Switzerland, during September 1981. It grew out of an informal studio collaboration between Queen and David Bowie, who happened to be working nearby. The recording brought together Freddie Mercury and Bowie on vocals with Queen's Brian May, Roger Taylor, and John Deacon.
"Under Pressure" was released as a single in October 1981 in the United States and in November 1981 in the United Kingdom. It later appeared on Queen's 1982 album Hot Space, which is why some listeners associate the song with 1982 rather than its original single release.
The song became Queen's second UK number-one hit and Bowie's third. Its instantly recognizable bass line is generally credited to John Deacon, although the exact development of the riff has been described differently by people involved in the recording. The song is also often discussed because Vanilla Ice later used a similar bass line in "Ice Ice Baby."
