This live version of Dazed and Confused is pretty good. It's fascinating how good the sounds are. The drums sound dynamite. They're just enormous sounding. And John Bonham is a very tasteful player. He makes the drum part sound huge and powerful by playing very specifically.
The quality of the bass sound in this video is also a tad surprising. Normally these old film versions don't have the hefty low end to really make the bass sound good.
Every electric guitar trick for making a guitar sound different is going on here. And I don't just mean the wah pedal. Flipping pickups and changing the position of the right hand all contribute to a wide tonal palate and dynamic range. And all the time the sound is fairly distorted, which oftentimes masks those kinds of details.
And, er, just as a warning -- the video cuts off abruptly at 10 minutes.
