Like a large part of the male populace in the US I grew and had my Zep and classic rock phase. Listening to most of that stuff now is like trying to enjoy Freebird with fresh ears, still classic but sometimes dated and not nearly as enjoyable; yet, I find that a lot of the Zep stuff and a few others really hold up and have a timeless enjoyablility. For me especially I still hear albums 3 and Physical G and think how fresh they sound. As per this thread, Ann and Nancy have been massive Led fans since the get go, especially Anne who basically says she started playing guitar because of Jimmy Page.
