Dazed And Confused - Led Zeppelin HQ (with lyrics) It wasn't just the torrents of notes, or the sensual moans, nor even the wild energy of Bonzo. The underlying concept was to try to capture the emotion of the moment in order to communicate it. The sound of the environment. That is the fundamental point. That's what the microphones placed at various distances, the skins lined with tin foil, the violin bow were for. Simple, yet effective tricks that changed rock. Distance is depth. And the Devil runs in between.
