This is a typical opeth song : unusual heavy guitar riffs, extremely melodic solo, good use of keyboard and bass and the combination of soft and death vocals. The transition of Mikael's vocals from whispering to growling and vice-versa is just amazing. This song from the album "Ghost Reveries" is based on satanic theme. The lyrics of the song shows the worship of satan; the call to satan. And my interpretation of the video is that it is about a boy who killed his mother and turned to satan except for the isolation years. Well, you can put forward about how you percieve this song.
