I'm only four songs into the new Led Zeppelin DVD and I feel the need to post.

On Dazed and Confused, he completely goes off the charts. He gives himself an extended solo, and by solo, I mean to say that everyone else in the band goes silent. He deviates from the base melody so thoroughly that you'd have no idea what song he was in if you heard the solo on its own. But somehow, somehow, he ties it all together and the song is seamless.

Then he plays a solo performance of White Summer. Holy shit, I can't possibly imagine how he worked that song out. It sounds like he pushed every bit of songwriting convention out of his mind when he wrote that song. I think his eyes were closed, and he swayed in the chair when the rhythm picked up.

Alrighty, on to song five.
