You most likely have never heard of Symphony of Heaven as it is a brand new band. Logan Thompson is the one-man band that is Symphony in Heaven. He has an instrumental called “Anno Domini” that is great. SOH released a song titled “Stratagem” that is primarily power metal styled up until the vocals come in. Pure death metal gutturals. It’s like Lightforce (pre-Mortification) and Mortification put together. The song is incredible. Go check it out here!
