In the summer of 1981, Queen was recording tracks for their tenth studio album Hot Space at Mountain Studios in Switzerland. As it happened, David Bowie had scheduled time at the same studio to record the title song for the movie Cat People. Bowie stopped by the Queen sessions and joined in. The original idea was that he would add backup vocals on the song “Cool Cat.”
In the end, Bowie said, ‘This is stupid, why don’t we just write one?’” And so began a 24 hr marathon writing session
The result – Under Pressure “Acapella”
Have a listen – the isolated vocal tracks of Freddie Mercury and David Bowie.
It’s pretty interesting to hear the song acapella.
