This is a newly released digitalized CD of the 1970 album, which, at the time, I didn't much care for when I first heard it. As a matter of fact, this is one of the few Led Zep albums I never had until I bought it in Sullivan, Missouri, at the Wal-Mart on Route 66.
It wasn't in the $5 bin like the others, but they had it on sale for $9. I figured, why not buy it and give it another chance.
Now, back in college, I scraped up enough money to buy the first two albums by them (although it seriously cut into my drinking funds). I heard a friend playing it at the frat house and liked a couple songs, but am sure what turned me off was the 4th cut, "Since I've Been Loving You" which clocked in at 7:24 and was slow blues. I hated blues music in college and for several years afterwards, but now really like it.
At a much older age now, I can appreciate that song much more, even though it bordered on jamming too much. (I still do not like jamming. The worst concert I ever saw was the Grateful Dead at Alpine Valley. I think they played four songs over three+ hours.)
