This is my favorite song of all time. I think it epitomizes Dream Theater's amazing style and musical prowess. If you listen to this song and it doesn't move you, then you may want to check your pulse because you might be dead.
from Metropolis 2: Scenes From A Memory, available on CD
This is one of the most beautiful songs I've ever heard. Opeth's music is powerfully passionate and it shows strongly in this song. Sounds like the kind of song that would be at the ending credits of a sad movie.
This is my favorite piece of classical music, so beautiful it often brings me to tears. You are strictly forbidden to go to your grave without having heard this song.
I've never been much impressed with Mastodon's music, but this song is fantastic. Off the new cd, "Crack The Skye." The rest of the album is decent, but Oblivion is the gem.
If you like progressive instrumentals, I urge you to give this song a listen. One of the best, most intense and melodically well-crafted instrumentals I've ever heard. Off their first album, "The 1st Chapter".
