Best 5 engineered rock albums?

Ghost_rider,

You're kidding about Steve Vai's the Ultra Zone right? All of Steve's recordings are done in his "home" recording studio and all his other recordings that I've tried on my system very mediocre to terrible. But, I don't think I've even tried Ultra Zone on my hifi since I was assuming it was like the rest of his recordings. I have it and will have to give it a listen.

My list:

Pink Floyd: "Dark Side of the Moon" or "The Wall"
Fleetwood Mac: "Rumours" or "Tusk"
Many ABBA albums
Buddy Guy: "Blues Singer" (OK, not quite rock, but I couldn't resist)
Most Steely Dan albums ("Gaucho" comes immediately to mind)

I cheated--there are more than 5 here--but, hey, so sue me. :)

ROBM321 well what did ya think?

This is a good discussion of course, but a bit off topic in my opinion. Should be placed at the "Best of" section.

Ghost_rider. I'm actually traveling now - but I promise I will post my thoughts.
