The first solo of Windowpane! My god, AWESOME!
Ghost of Perditition, the clean parts and A Fair Judgement, when the second part of heavy shit comes in... gotta love it!
Pretty much every Opeth track except the majority of GR is filled with moments like this for me, but these are the strongest examples:
April Ethereal - All of it
The Moor - 3:20 - 6:00
Dirge For November - ''The Omen Showed''
Blackwater Park - ''Sick liasons...''
A Fair Judgement - ''Lost track of time''
Ghost of Perdition - ''If one cut the source of the flow...''
I dont think anyone has said nectar yet. "and guide me through your warped labyrinth, to the well of sin, I swear i will always love you." that part kills me every time.
