This is a black metal band that broke up (after only 1 album, sadly) because its singer was literally insane, and sent to an asylum. They're one of the most underrated black metal bands ever. I think they'll go down like Cynic as one of the greatest 1 album bands in extreme metal history.
Then again, they're from Sweden, and all the famous black metal bands are from Norway. They were just destined to be underrated.
