Well, I'm back and sobered up (you wouldn't wanna know the price of a pint in Norway, Tim - it's preposterous)...As for Michael's original question, I'm a bit hard-pressed. I'm all at once!
I am a John Williams and Danny Elfman completist (the word speaks for itself). I like to own every score that has an historical significance, even if it's not exactly my "cup of tea". I like to own every score, which musically I like(!). I like to own scores specifically in the orchestral adventure mode, but eat everything (and I mean EVERYTHING...almost). Whether this makes me a collector, an accumulator or whatever, I don't know. As my own article touched upon, it's VERY hard to make categories about this stuff and generalisations in general(!).
What would make my collection complete? Every Williams and Elfman note that I don't own..
A gem in my collection? If gem is valued by rarity, I've got a few - like SUGARLAND EXPRESS, DIAMOND HEAD, MAN WHO LOVED CAT DANCING, WITCHES OF EASTWICK, ACCIDENTAL TOURIST, SPACE CAMP etc.
But my ultimate, personal and emotional gem is still my favourite score of all time - RETURN OF THE JEDI.
