Good analysis.
In your opinion, which instrumental is better - "Orion" or "The Call of Ktulu?"
Orion. Hands down. That bass just sitting there at the beginning... then the drums come in from a vanishing point, then 'tap tap tap tap TAP TAP' and ALL of the guitars come in... WHAAAA... then Hammett just WAILING in the middle. Oh yeah.
Don't leave 'To Live Is To Die' out of that short list. It's better than 'Call of Ktulu' in my humble opinion.
Of course, this is ALL from memory... I really need to replace my twenty year old cassette tapes of these guys with CDs and start listening to the old albums again. They were my favorite musicians by an order of magnitude for a number of years.
