Hey Hey Mama

Led Zepplin and Rush are both awesome and they're kind of similar in that I think they both were pioneers and both of them had some of the most skilled players ever. There's no topping Neil Pert on drums, and Jimmy Page is pretty huge for a reason. These albums both have long periods of instrumentals but unlike 2112, Zepp 4 is all singles. I like Zepplin 4 a lot lot more and this album was much more successful than 2112. 

I like to listen more than analyze which I think Zepp 4 may seem so much more appealing to me.
