3 Black Sabbath Black Sabbath Black Sabbath were a Heavy Metal band formed in Birmingham, England in 1968 by guitarist and songwriter Tony Iommi, singer John "Ozzy" Osbourne, bassist and main lyricist Geezer Butler and drummer Bill Ward. more.

Black Sabbath didn't influence the NWOBHM. On the contrary, Black Sabbath were influenced by the NWOBHM and in 1980 Black Sabbath radically changed their sound and style - from heavy blues rock to heavy metal.

Judas Priest and Iron Maiden didn't sound like Black Sabbath (bluesy, slow and/or quite simple songs) - they sounded like Rainbow and Deep Purple (non-bluesy, fast, complex, technical and classically inspired songs). The Trooper by Iron Maiden sounds like Highway Star by Deep Purple and not like Iron Man by Black Sabbath. The NWOBHM incorporated massively and irreversibly Ritchie Blackmore's metal DNA into the metal sound.
The Heaven And Hell album by Black Sabbath (1980) sounds pretty much like a Rainbow album. Black Sabbath even hired the most talented metal musicians discovered by Ritchie Blackmore - Dio (Rainbow) and Ian Gillan (Deep Purple) on vox, and Cozy Powell (Rainbow) on drums.

Simple they created heavy metal, they had a large influence on all of the NWOBHM bands and all metal bands today. They also created 2 major metal subgenres without even knowing it; Stoner Metal and Doom Metal.

Um, sorry dude. Remember Paranoid, from 1970? Sure, some songs on there were more blues-styled, but the title track, War Pigs, and Iron man reduce the blues for a heavier sound.

4 Death Death Death was an American death metal band formed in 1983 by Chuck Schuldiner.

Most extreme metal band either, they popularized the satanic image that bands try to replicate. They created Black Metal and coined the term, Black Metal. They were the first metal band that scared people, and made people think they were evil. - ryanrimmel

Ritchie Blackmore did something revolutionary: he first created rock songs based on scales typically used in classical music. The songs sounded non bluesy, in contast to all rock music back then. That was the template for metal music - heavy metal is a non bluesy genre.
All other rock bands used mostly blues scales to create rock/hard rock, or - in the case of Black Sabbath in the 70s - to create heavy blues rock.

Besides, Deep Purple introduced some other important features of current metal:
Introduced double bass drumming in metal;
Introduced theatrical/operatic vocals in metal;
Introduced ear raping screams in metal;
Produced the loudest sound of the 70s;
Created the fastest songs of their time;

No doubt, Deep Purple is the most revolutionary metal band.

Progressive Metal was around long before Dream Theater with bands such as Queensrÿche, but Dream Theater popularized it. Metalheads were either kept the fact that they liked prog a secret, or hated prog until Images and Words came out. They blew up and suddenly Progressive Metal was on the rise and everyone wanted to be like Dream Theater. - ryanrimmel

The Contenders

They were the first band to mix Punk with Metal, and also became a major influence on Speed Metal and Thrash Metal. - ryanrimmel

To be more precise, they mixed Punk with Rock N Roll - they've never been a metal band. They probably influenced thrash but not speed metal (speed metal is a subgenre of power metal with gorgeous operatic vox and Motorhead are definitely far from that). - Metal_Treasure

12 Slayer Slayer Slayer is an American thrash metal band from Huntington Park, California, formed in 1981 by guitarists Jeff Hanneman and Kerry King. They rose to fame with their 1986 album Reign in Blood, and is credited as one of the big four of thrash metal bands, the others being Metallica, Megadeth, and Anthrax. more.

Kreator's Endless Pain and Pleasure to Kill were FAR more revolutionary. Destruction was also more involved in early thrash and black metal.. And "Slayer spawned death metal with RiB"? Give me a break. Darkness Descends was more "brutal" than Slayer. In fact, death metal was spawned by the innovative elements of Possessed and German thrash metal.

They are the most aggressive, fast, and evil sounding Thrash band ever. Every thrash band wants to be Slayer
