Just listened to the Led Zepplin DVD (two discs - not sure when released). The most interesting part of the visuals was the comparison between disc one and two. In disc one (recorded at Albert Hall in 1970) the guys were not polished yet - their hair was long and unkempt and their clothing looked slept in and off the rack. In disc two they had obiviously hit the big time - Robert Plant has permed hair, and Jimmy Page's hair is feathered and both are wearing the tight clotes of rock stars. Fortunately the music is great throughout. We are used to today's absolute crass commercialism in the music industry. I guess it was beginning to creep in even with the freaks of the 70's.
