My older brother, late 70s, had LZ IV. I heard peeps talking about the band but I never listened to them. Then I did. I thought this was so different from everything else. They were my stepping stone to hard rock, metal, and then punk. Once i hit my late 30s and the internet exploded I started listening to all of the boots our LZ friends would post. Those are the be all end all. The 3 hours of lunacy. The hammer of the gods. I now seek out out obscure late 60s early 70s hard rock, hard blues, heavy psych hoping that there might be another Zep I missed out on. I haven't found it yet but I have discovered some gems that I never would have discovered if it wasn't for Zep. You can take my collection of over 1000 cds and vinyl just leave me my Zep.
