On Zep:
I used to be the definitive Led Zeppelin fan.
I've developed a less uncritical attitude, and have come to the conclusion that they've done a small number of absolute classics (When The Levee Breaks, Good Times Bad Times, In The Evening, Kashmir, Trampled Underfoot) and a large number of horrible, cheesy, stinkers (The Lemon Song, all of Houses Of The Holy, Stairway To Cheese, Going To California, Four Sticks, most of Presence, In My Time Of OH PLEASE MAKE THIS SONG END NOW).
Jimmy Page is a fabulous guitar player, and Robert Plant is a reasonable singer, but overall Led Zeppelin - The Hype is bigger than Led Zeppelin - The Band. JPJ is technically excellent, but probably one of the most boring bassists ever to live. The true star of Zeppelin was the brilliantly inventive John Bonham.
Best thing to come out of Zeppelin? Godflesh.
