pi against relative newcomer tau. Wherever side of the fence your math club's allegiance may lie, a quick listen to Michael Blake's newest nerd composition could have your circle singing a different equation. Perhaps spurred by the copyright brouhaha that yanked his earlier musical extrapolation -- What Pi Sounds Like -- from the YouTubes, Blake set this interpretation of the controversial constant to 126 decimal places and let'er rip at 125.6 bpm. What follows is a not-unpleasant symphony that should have Bjork's producers calling for a collaboration. Full video for the prog-rock nation after the break.
