Eh, I'd like to think Slayer's early years had a bit of influence on hardcore, if for no other reason than the speed.

A little bit, but not much to make a difference.

So much for this thread.

We really have a problem regarding following through with shit around here.

How the FUCK did we decide to leave Welcome To Hell out of the top 10?

Maybe it wasn't the most important, but it was surely the first real extreme metal album that kickstarted a generation.

Not the first wave of hardcore but thrash metal certainly had an influence on mid/late '80s hardcore, particularly Slayer's more "straight forward" brand of thrash rather than Metallica's ever expanding progressive tendencies.

Well that's what I meant by hardcore. Most of the classic hardcore bands had already put an album out by the time Slayer formed, let alone made an album.

Should To Mega Therion count as Frost's debut?

Yes

Yes.

Any problems with the current top 10?

1. Black Sabbath – Black Sabbath
2. Ozzy Osbourne – Blizzard of Ozz
3. Metallica – Kill 'Em All
4. Dio – Holy Diver
5. Venom – Welcome to Hell
6. Iron Maiden – Iron Maiden
7. Morbid Angel – Altars of Madness
8. Celtic Frost – To Mega Therion
9. Diamond Head – Lightning to the Nations
10. Possessed – Seven Churches
11. Candlemass – Epicus Doomicus Metallicus
12. Death – Scream Bloody Gore
13. Mercyful Fate – Melissa
14. Helloween – Walls of Jericho
15. Exodus – Bonded By Blood
16. Slayer – Show No Mercy
17. Emperor – In the Nightside Eclipse
18. Napalm Death – Scum
19. Cynic - Focus

Except for Ozz and Dio being a little too high, I really like it.

One other thing - does Seven Churches really need to be that high?

No way in hell should Dio be above the first Maiden album.

Yeah I was thinking that too.
HD was huge, but Iron Maiden was kinda the benchmark album for the NWOBHM.

Iron Maiden was a turning point.
Holy Diver was merely a continuation.

I took that from the main albums list. I don't see a reason why it should be different.
