Your favourite riffs from Evile

I'm really not sure what a riff actually is... so don't kill me:erk:

But is the song Devoid Of Thought from 4:35 a riff? If so that's amazing and part of my favourite bit on the track:kickass:

I bet I'm totally wrong now:cry:
 
i think nosophoros because it's so insanely fast
the second half of metamorphosis
the chorus of infected nation
Devoid of Thought 0:30
we who are about to die 4:22
enter the grave 0:26
