mirrorthrone-Florilège Lunatique Occultement Révélateur et Néantisation Caduque Engendrée has the fastest ive heard. then there is various nile. and Kai hahto is damn fast.

Mirrorthrone and one of Vlad's other projects Unholy Matrimony best utilise drum machines for speed. Agoraphobic nosebleed though... dont use it ........as well

as for real drummers
Death Reveals - the Berzerker - the snare rolls are insane - you know the ones around 1:25ish, then you realise he's doing it one handed and it's even more insane

Churning the Maelstrom - Nile, Tony rips the drum machine apart for this, crazy blasts and double bass.

Comforting Prejudice - Beneath The Massacre - good lord. all that needs to be said

Procession of Aeons - Abigail Williams - good use of a gravity blast (i think it's a gravity blast, i know bugger all about drumming so i could very well be wrong)

Enraptured By Evil - Akercocke - gotta love ol Dave.....

INTERNAL SUFFERING
I have loved Awakening of the Rebel since I heard it, and that drummer is fast. Obviously not the fastest drumming ever heard, but it's really fucking trying.

I think you're wrong sir. Here's a better equation...

Berserker > Godly Fast.
