The poet and the pendulum (Demo version) - Nightwish
https://www.youtube.com/watch?v=2oECYCV5-5wKinda sounds like "early Nightwish before they got big" in some ways. It's obviously without all the really fancy choir and orchestra stuff and kinda unpolished, but it's still got some weird kind of charm to it.
I also love the spoken part at the end of "The pacific", tho more because of Marcos voice than because of what's being said. This song actually used to be EVEN DARKER than the final version currently is.
Poor poor Tuomas.
