Don't say the band whose sound they are obviously trying very hard to ape? OK.
So just because Diamond is a Halford wanna-be, that means they sound just like Judas Priest in general?
Fate mostly played a much slower and more menacing style of metal.
Honestly they don't sound that distinct from Diamond Head combined with Priest (and not a little derivative and similar to what Metallica and then Megadeth sounded like).
Diamond Head were more on the 'hard rock' side of metal with a big Zeppelin influence thrown in the mix. There was nothing hard rock or bluesy about Mercyful Fate, they were metal straight down the line.
The vocals are basically a direct attempt to ape Rob Halford and to deny that is absolutely silly (regardless of the "aesthetic").
Yes, the vocals, which are merely one aspect of the entire sound.
I'll give you lyrics but only because I can't be fucked to look up who started the aggressively juvenile lyrical trend that they embody.
Your opinion of it being "juvenile" doesnt change the fact that it became a HUGE part of most extreme metal that followed.
It was really Venom that started it, but MF were largely the ones that most bands were imitating stylistically.
I don't know what that really gives you. Sonic influence matters far more. Explain to me who you think took major influence from Mercyful Fate who actually matters?
Practically the whole of the black metal genre itself?
Not to mention sounding very similar to Venom themselves in terms of the heaviness and the tempo.
Am I arguing with a box here?
Venom had a VERY big punk influence on their style. Just because MF played some fast songs doesn't mean they are similar to Venom...I really don't know where you're getting this.
