Ayreon - The Human Equation
This is a prog rock concept album from dutch musical genius Arjen Lucassen. It's about a man who's been in an accident and in a coma. He must get to know his inner emtions which is sung by the best vocalists in the prog/rock/metal scene (they think it's an honor to be on a Ayreon album).
It's by far my favorite album of all times and I hope more will listen to it and appriciate it
Edit: Got a smaller picture. I also think this album is really well recorded. I use this album often as a reference of what sound I like.
