Everytime I think about it, my personal list changes completely, depending on what mood I am in and what I have been listening to. Right now, the album openings (BTW I don't mean the openER as in the entire first song, I'm talking strictly about the way the artist leads the listener into the album) that would come to mind for me are:
1. Opeth - In Cauda Venenum (perfect mix of initial suspense followed by epic show starter)
2. Steven Wilson - To The Bone
3. Little River Band - Sleeper Catcher (CAUTION: I mean the version that starts with Fall From Paradise including the orchestral intro part, which I attached to this post. If you don't know this album and opener, taker the time and give it a spin. This album is one of the big masterpieces of 20th century rock music, I kid you not.)
