Most Kickass Riff of all time?

Not to sound cliche, but

Slayer - Angel of Death (intro) is probably the best.

Notables:

Dimmu Borgir - The Night Masquerade (pre-chorus)
Carcass - Heartwork (any riff from the whole album really)
Hypocrisy - Roswell 47 (intro)
Hypocrisy - Paradox (verse and chorus)
The Misfits - Cough / Cool (one note on a keyboard yeah!!!)
Pantera - Cowboys From Hell (intro)

Classics:

Any Hendrix or Zeppelin.

Haha I'm really glad to see this song make the list..Acid Bath were truely a grand fivesome..
 
Carcass - Heartwork
Cannibal corpse - Devoured by vermin (when the breakdown kicks in)....and anything else by cannibal corpse

and also Cryptopsy - Phobophile....when it kicks in straight after the piano/bass intro
 
Man, I'm going to say that the most kick ass riff has to be Acid Bath's Tranquilized. It's just a damn good riff.
 
I know that i will get hated for this but.... Machine head "old" damn that is a fine metal riff.
Slayer "reign blood" and "south of heven"
Black Sabbath "symptom of the Universe"
At The Gates "Blinded by fear"
there are far too many for me to list!
 
The ending riff of Bodom After Midnight, second song on Follow The Reaper, by Children of Bodom...

They're not the most intelligent metal band, but that riff owns...:headbang:
