Not a whole lot for me to say here except this: somehow, impossibly so, this album gets the balance of acoustic and electric rock 100% perfectly right. That's harder than it seems and if you don't believe me, then have I got a Foo Fighters album for you! (It's "In Your Honor." Disc 2. The one that's entirely acoustic/softer rock. Try it if you dare.) I think it's because Zep can do more than one style of acoustic rock, so that when they slow things down on this album it still feels moody and heavy enough that it just *feels* like hard rock even when it ain't rockin' hard. 8 songs, 43 minutes, and all of them are good. Just hard to find fault in that equation.
