Your shivering Opethian trance

Demon of The Fall: 4:26 and continues on from there.

Black Rose Immortal: 13:30 (I believe) Greatest riff ever recorded. Godly.

Bleak: "Mist ripples round your thin white neck" and so on.

To Bid You Farewell: "In my own ashes, I am standing without a soul"

Ending Credits: The whole damn song.
 
Although it isn't my favorite moment, it has to be mentioned:

The part in Master's Apprentices where they go from the soft clean "beach boys" segment, and then suddenly that monstrously heavy riff hits out of nowhere and Mikael begins growling in an evil, low, demonic voice.
 
Demon Of The Fall: 4:56 - 6:07
April Ethereal: 3:38 - 4:01 and then again at 6:45 - 8:41
The Amen Corner: 5:33 - 6:35
When: The Entire Song, I begin the trance just as the last of the Madrigal interlude ends.
