The Top Ten Best Canadian Extreme Metal Bands
Thrash and technical thrash are officially extreme subgenres so Annihilator are eligible. And they are great, especially their guitar work, drums, songwriting and lyrics. - Metal_Treasure
I have a slightly different view in extreme. Doom metal is also officially extreme too. Annihilator doesn't have a very extreme sound to me - ryanrimmel
Yes, it is extremeLY AWESOME!
