I was watching the documentary "Until the Light Takes Us" and there was a part where Fenriz was at a shop playing King Crimson's Epitaph (I had to shazam it, as I had never heard it and wasn't familiar with King Crimson.) I loved it. I got their debut and Red as it was recommended by the record store I was at. I'm looking for more stuff along the lines of Epitaph, I love the super progressive sound they had. I haven't liked much of the progressive metal I have heard so I think I am looking for rock, not metal. Anybody have any suggestions?
