Best 5 engineered rock albums?

Thunder and Lightning - Thin Lizzy
Powerage - AC/DC ( Highway To Hell had slicker production but Powerage has the best/clearest bass I've heard on a rock album.)
No Rest For The Wicked - John Osbourne
I, II or Zoso - Zepp.
Bad To The Bone - George Thoroughlygood

I have to disagree about the Thin Lizzy and Ozzy albums. The best sounding Thin Lizzy is 'Chinatown,' and the best sounding Ozzy is 'Diary of a Madman.' Go for the original LPs for both of these titles...

I have avoided this thread for a awhile because of the word "best" in the question (and fellow 'goners know how I feel about that Pandorian word). Without a desire to change the direction of this thread, had I been asked from a "favorites" point of view I would have answered it in terms of some of my favorite rock engineers, those that I feel truly pioneered new directions and approaches to the craft, they would be, in no particular order:

Eddie Kramer
John Leckie
Glyn Johns
Geoff Emerick
Butch Vig
Andy Johns

But, of course, I was not asked that question.

Nice list. I would agree with it!

Lol guys, thread title should be: Top 5 rock albums thru your preamp.
