World Downfall - Terrorizer. Basically invented deathgrind

Left Hand Path - Entombed. The first big album from the Swedish death metal scene.

Beneath The Remains - Sepultura. I know you have them under 1986, but this was a huge milestone album.

1994:

Burn My Eyes - Machine Head.

Others:

Cannibal Corpse probably needs a mention. I'd go for Butchered at Birth rather than Eaten Back to Life.

Carcass needs a mention. They invented goregrind with the first two albums, Necroticism was voted Terrorizer magazine's album of the decade for the 1990s (it was highly influential), and Heartwork blah blah... melodic crap.

Slipknot?

That's just from a quick look, but that's a good fun, cool sort of list!

One that immediately comes to mind that not's there is Sad wings Of Destiny - Judas Priest.

-------------

Cannibal Corpse were the biggest death metal band in the world (probably still are) and managed to get in the Ace Ventura movie in 1994. There was a lot of mainstream interest around them, particularly for their lyrics. Tomb of the Mutilated was also the first album I remember which had a parental advisory warning for artwork as well as music. That was big.

Beneath The Remains was the album where people noticed Sepultura. They were almost completely unheard of before that. They renewed interest in thrash, and opened up Brazil and South America in general as a reliable source of metal. They were spoken of as the next Slayer. It's sort of hard to convey now what a big deal it actually was.

Burn My Eyes was a big deal at the time too. Like Chaos AD, it was a stepping stone from thrash to groove metal, and even in to nu-metal. Same as Beneath The Remains, it's hard to demonstrate what a big deal they were at the time.

These are just a couple of my observations as an aging metalhead. These were milestones I remember. It's your list, so do what you may! I'll have a closer look when I have a bit more time.

Rage could also be mentioned for the same reason. 

And while I think about it, Myrkur would also be worth a mention. Possibly a controversial one among the purists out there but her largely clean vocal take on black metal is unusual. 

^ @ Adam, thanks for the suggestions! I considered Blind Guardian but Helloween beat them to the power metal thing. I can't include everyone only firsts and interesting unique examples. I own all Blind Guardian albums so i'm familiar with each album. Epica sounds like an interesting case.

I'll check into Cruachan (which i'm not so familiar with) and the last two you suggested, Adam. I'm sure there are many oddballs out there i've never encountered. I just thought of quite a few yesterday that i added myself!

I'll have to chew on all this later.

@Vim. I dunna, Cannibal Corpse may be the most popular death metal band but they don't have a single album that was unique really. They weren't the first death metal band and even the parental advisory first goes to 2 Live Crew not a metal band. Sepultura might be a good consideration. Burn Your Eyes wasn't even close to the first groove metal. Pantera wins that distinction hands down. I own most Machine Head albums and i don't find them innovative or unique but thankis for the suggestions!

Do keep em coming :)

To not include them does a disservice to and under-represents the whole genre. That's my final pitch to have them included and if you still don't think they should be mentioned then I'll say no more about it, but I think you're very wrong by excluding them from a project like this. 

Speaking of Sabbath, your Paranoid entry has the first letter of the sentence missing. 

THat's a good suggestion. I'll probably add them! I'll fix the Sabbath mistake :)

So which Blind Guardian album would you consider a single moment when the band added something new to power metal? I know they added choirs and more epic classical elements on Tales From The Twilight World. They were certainly more progressive than Helloween.

The first two albums are obviously more speed metal. Tales From the Twilight World is their first power metal album but it still has speed metal elements. On Somewhere Far Beyond they refined this sound. However either would be an acceptable inclusion. As an aside they are also a good example of a metal act who knows how to do soft ballads right. 

You've also got to remember that Helloween's Keeper of the Seven Keys albums actually have a very old school sound very like trad heavy metal. They don't fully represent the refined genre of power metal any more than early Black Sabbath represents fully refined heavy metal. Helloween also drifted from what they'd created heavily through the remainder of Kiske's era. Some may call Pink Bubbles Go Ape power metal, but it's really only got a scant few elements and Chameleon is pretty laughable to even consider a metal album. It was only when Deris took over that they returned to power metal and produced anything that might be considered in the same harder power metal league as what Blind Guardian were doing. By that time Blind Guardian had released both Tales and Somewhere and further refined the genre as a whole along with its harder German sound. Of course in terms of refining a sound, you can't discount Gamma Ray either, although I don't personally consider them landmark until Kai Hansen became the lead vocalist for Land of the Free. 

OK. You convinced me. I'll add a Blind Guardian album. Personally it's their ballads i don't like. I much prefer Helloween :D Speaking of which i watch some footage of their tour from last year and damn Kiske can still sing like a mutha fucker despite porking out over the years. Great idea to have both vocalists share the limelight. Gamma Ray, no. THis isn't an exhaustive list. Just one that represents some sort of innovation in the metal universe.

For black metal, you might also consider the debut Ulver album. Everything I spoke of for Myrkur can actually be traced back to that, especially the opening track which may be the first example of a black metal track with clean vocals. 

You might also cover USPM a little more. You have some proggy types but that's not extensive enough. Sirens by Savatage is often credited as the first USPM album and would be a good pick, with other key early releases in its history being Warlord's Deliver US EP and Jag Panzer and Omen's debuts. Bands like Riot and Iced Earth took it even further in the late 80's/early 90's respectively. 

Here is a great link about USPM that you will probably find more useful than I can convey here:  https://rideintoglory.com/marcos-guide-to-uspm/" rel="nofollow - https://rideintoglory.com/marcos-guide-to-uspm/

Metal is not her usual sound as she genre hops. But in 2017 she released this one:  http://www.metalmusicarchives.com/album/chelsea-wolfe/hiss-spun" rel="nofollow - http://www.metalmusicarchives.com/album/chelsea-wolfe/hiss-spun

This is one of those releases that had the RYM genre voting crowd very torn over what it actually was. But it's mostly been settled as a doom metal album. 

I'll have a think about any that may fit here, but for now I'll second Ulver's debut. 

Of course black metal is really quite diverse with a lot of innovation happening and not necessarily in the best known acts that you can easily do a list like this that was just black metal specific. 

^ thanks Nicole

i have gotten many great suggestions here and on RYM.

still checking out some of the suggestions.

Adam, spinning Hiss Spun right now. Yeah, different for doom metal for sure however i'm seeing some of her previous albums are labeled doom metal as well. Will look in to it. Thanks
