Some of the metal-education post needs to be fixed. There are some terrible assumptions in there.

Care to enlighten us all then?

-Melodic death metal does not have a "better sound quality."
-The doom metal section fails to mention anything about traditional doom besides Candlemass in the examples part of it.
-Entombed are not melodic death metal
-The Haunted and Kreator are not similar whatsoever and The Haunted didn't borrow anything from Swedish dm.

....there are others

Judas Priest as founder of metal? i don't think so. Black Sabbath did. Tony Lommi Sabbaths lead guitarist lost one of his fingers working at a plant, and he made a fake one and when played on the guitar as he strummed the chords is made a deeper darker sound. that was the birth of heavy metal.

I definitely agree with the part in bold.

But the rest of your post looks to be total bull. First, Iommi didn't lose a finger but the tips of two fingers on his right hand (middle and ring, I think). He played left-handed. The plastic finger tips he created had nothing to do with the way he hit chords since they were on his fret hand. And, in any case, it's generally the progressions themselves (chromatic, tritone, modal scale), which gives metal its character, not just how the chords are hit.

Next, you'll be saying that his plastic finger tips gave birth to palm-muting (or pizzicato)...

well you got most of it right. the only thing with his prosthetic fingers was that he had to tune his guitar down giving it that deeper metal sound.

That happening just sounds metal as it is. Hmmm I guess I'll look up some videos I never really paid attention to his fingers.

Probably at it's peak between 1976 to 1980.If any group that charactaristed Pomp rock it would be Saga (Canadian).Other than that Styx (American).It was a term used by the press by for groups who sounded kind of Prog but never really took their music on a journey like Prog groups did.The music used short keyboard/guitar breaks instead of extended ones.It is was mainly uptempo/positive sounding - it was FM radio friendly.Arena rockers Journey,Boston & Kansas etc I would consider associated, Magnum had better song/musical craft to fit in easily with Pomp but related (Melodic Heavy rock).Pendragon - definately Neo-Prog.In the early 70's Rush were often refered as Pomp as well,but not as FM radio friendly & had better song/musical craft again.It basically went out of fasion when new wave & then neo-prog (about '82) emerged.

I would say Sabbath were the originators of the early stripped down louder blues/hard rock based Metal sound [based on Led Zeppelin's sound or even King Crimson's - 21st Century Schizoid Man (track)]- which had a slow to medium tempo.Judas Priest developed a new sounding metal from their early Heavy Prog sound stripped it down speeded up the tempo & made it more abrasive to form a sound associated with 80's NWOBHM sound (Iron Maiden). almost Trad Metal now.

The origins of prog rock have often been linked to the beginning of the psychedelic scene that flourished in both the UK and US, starting as far back as 1965. Amongst popular bands The Beatles were pioneers with albums like Revolver, Sgt.Pepper, and Magical Mystery Tour and surely had a profound influence on their English followers in Crimson, Yes, Genesis, Floyd and the rest...up until today with bands like Radiohead Porcupine Tree, and Three (3)
