First of all, allow me to stress that I am not, repeat not, a Led Zep fan. I've never quite understood why this band is worshipped the way they are, and I definitely do not think Jimmy Page is a god. I don't get it. They're a good band, sure, but come on. Having said that, I do think that John Paul Jones is a talented arranger, and Bonham was a powerful drummer. OK - I've established some basics.
So why did I ever buy this album? I'm not sure. It was 1979 and practically every song on In Through The Out Door (1979) was in heavy rotation on KQRS, the local album rock station. After buying the album I listened to it for a few months before abandoning, and eventually selling it, to one of the local shops. Tonight at the record store I ran across a copy of the album in its original brown bag wrapper and said "ah, what the heck". So I'm listening to this album now for the first time in over 25 years and it's pleasant. I like everything I hear, although side 2's ten minute opener ("Carouselambra") is probably unnecessary. There are definite highlights though, like "In the Evening", "South Bound Saurez", "Fool In The Rain" -- OK all of side 1.
Let's see if it takes another 25 years for me to listen to it again.
