I was a teen in the 1970's and feel like this and all Led Zepellin music was my soundtrack for the whole decade. I know all of the songs on all of the albums by heart. This one is special as you say - it was so raw different than anything that came before - regardless of Rolling Stone's bad review.

I remember this time when the mainstream wanted to fight the band's excellence. But everyone listened to it and loved it all the same.

Thanks for the trip down memory lane. I have some catch up listening to do now :)
