Just listened to it tonight. I was in Cimmerian bliss (if such a thing exists) for about 2 hours listening to the first two disks (the third is a re-release of the old '82 ST which we are all familiar with) as I was working out. It really transported me to the immeasurably ancient Hyborian Age when Conan stalked the world, pitting his sinews and steel against nameless abominations and scheming villainy.
Aside from the main theme (heard at the beginning, in the orgy scene when Conan fights Rexor and Thorgrimm, and at the end), my favorite of all time is the beautiful choral piece with accompaniment ("Las Cantigas de Santa Maria", track 21 on the 2nd disk) heard as the three thieves mount the Tower of the Serpent and steal the Jewel as a maiden readies herself to be the giant snake's next snack. To me that scene is the epitome of the Sword and Sorcery genre: dark, mysterious, unsettling, erotic, complete with unnatural fauna and unspeakably evil cults. I have waited 31 years to hear that with high-end stereo speakers. Thank you, Basil, and thank you, Intrada!
So many impressions, and so many comments I've jotted down. I'll have to organise them all and produce them later, time allowing.
If you love the movie like I do, and regard this as one of the best soundtracks ever made, you will not be disappointed.
