Query: Welcome Home rocks the world

It took me a while to get into Coca, but after a few listens it became one of my favorite bands ever. I have since bought all of the previous albums, but Burning Star IV continues to be my favorite. It has some awesome songs like 'The Suffering', but "Welcome Home", I am convinced, is the greatest song ever written. I also love that Coheed has a story behind it. I've never been able to get my hands on the books, but from what I've heard it follows along with the music. That's a really neat idea because it brings the music to another level. Anyway, if you like heavy music with interesting sounds and lyrics definitely give CoCa a listen.
