Yeah, I have to say that that song had a sort of melody in the guitar tune. The guitar line sounded like early Iron Maiden, sort of pahntom of the opera type stuff, the maiden with Dianno singing. I will say this, that song with the singing being deep bass and also non-human-esque and the fast paced bass riff and non stop fast drumming is clearly heavy metal or rather, to my ignorance, black metal. See if someone played some Billie Holliday and then played that song there, you could say, ` I know which of those songs is Jazz and which one of those songs is Metal` but how do you put it into words, or a definition?
In my opinion, the band UFO are not heavy metal, they are very close to being heavy metal, or maybe they are heavy metal, some of it is, but whichever, they do not sound at all like the `Sacrementum` band. There is a HUGE diference.
