Half filler half killer
Seriously though, having grown up on Classic Rock Radio, and living with Zep fanatics in college, I feel like I honestly don't ever have to listen to them again.
I mean, this is a solid album to be sure. Stairway To Heaven is a masterpiece, and I LOVE When the Levee Breaks.
Rock n Roll is all kinds of awesome, but truth be told, I've always been hot and cold on Black Dog. I've never thought it to be all that great.
Misty Mountain Hop is filler all the way, and Gong To California is cool enough. But Battle Of Evermore and Four Sticks have always been skip worthy. And Fuck the self fellating Heart version of Evermore too!
