Haken - For those of you that like Progressive Metal music check out these guys
I only recently discovered these guys. I really love the song "The Architect". It starts with a crazy instrumental but changes style quite a bit and is overall an excellent song. I shared three videos here... The Architect I only found in audio format on Youtube.
** THIS SONG IS AWESOME vvvv **
EDIT: The vocals and song change a lot pretty close to the 3 minute mark. Great stuff!
