Holy crap! How am I just now finding this?!

"Led Zeppelin performing one of their earliest recorded sessions, for Denmark's Radio."

1969. 31 minutes. And the audio is amazing. Plant's voice is young and fresh. Page is....well...FANTASTIC. See 22:00-24:00 Did Page just erupt from the ground as a guitar god? Was there ever a learning period?

(yeah there are several sections in this where they needed an editor. 'Going on too long in that bit!")

Love the air guitar that Plant does at 30:00.
