Recycled Air
If you write long enough, you collect so many ideas that can be retreaded to fit perfectly into some other collection. Apparently Breathe , the opening track on Dark Side of the Moon , was repurposed from the soundtrack from the 1970 documentary The Body . Its pedigree is film music, which set the mood for the whole album--and music history. The first Earth day was in 1970, the official start of The Environmental Movement. The juxtaposition of images of smokestacks in the countryside, and other downer images--set against Roger Waters' typical sardonic ironicism, cajoles us to breathe in the air. (See end of clip)
