I was happily reading Sasha Frere-Jones' blog about CMJ, when he dropped this linkbomb on me, asking, "If you do not think there is any drumming in this cover of 'Satisfaction,' watch Björk’s hips. Also, a question for physicists, audio engineers, and clerics: how can Björk sing so loudly and not drown out Polly Jean Harvey, even though Harvey never raises her voice particularly high? And a question for music lovers everywhere: why has this song inspired so many good covers?"

And the big one: How could I have been unaware of this clip?
