Aye. Just as the title implies. On which of Cliff's three albums with Metallica do you think he shined the most? Personally, I'll say Master of Puppets. His diversity really shows when going from Sanitarium to Disposable Heroes - a simplistic 'groove', if you will to blinding fast riffage. And, of course, Orion - Cliff's greatest achievement as a musician. IMO. And a quick little question - who wrote The Call of Ktulu? I've heard Cliff a lot, and once in a while Dave.
