Black Dog/ Misty Mountain Hop

Here's a beautiful copy of the second pressing, which has the Warner Communications logo in the perimeter print. There really hadn't been anything like this before, and nothing but pale imitations since. Of course, there haven't been any musicians like John Bonham and Jimmy Page, or vocalists like Robert Plant. Not that this is the very best thing they did together, but it's surely their hardest-rocking single.
