"Breathing" is a song off Bush's 1980 album "Never for Ever," featuring backing vocals by Roy Harper. The post-apocalyptic ballad was the lead single from the album, and Bush said it was inspired by a documentary she saw about nuclear war. "I suddenly realised the whole devastation and disgusting arrogance of it all. Trying to destroy something that we've not created – the earth," she said in a 1980 interview. "The only thing we are is a breathing mechanism: everything is breathing. Without it we're just nothing."
