Frederick is an amazing guitarist, take my word for it. Arch Enemy's newest was sub-par, but he didn't write any of the music for it. If you really want to see the man's career highlight, check out Krux. They were formed with Leif Edling from Candlemass. Krux II was released last year, and is one of the most stellar doom metal albums of recent years. Akesson's solos are breathtaking, you should check it out if y'all get the chance!
