Have you ever wondered how drummers like Joey Jordison from Slipknot can get so many BPM's in on the bass drum when he's playing ? I have so... I looked it up on Youtube and this is what I learned so far.

although some deathmetal bands pull it off, its not my cup of tea... a buddy of mine ive played with before is now playing with Dimmu Borgir, they did a liveshow in colaboration with a symphony orchestra and a gothic choir here at the biggest venue in norway, Oslo Spectrum. That show was fucking amazing even thoug the blastbeats where flying, hehe...so it can be highly musical as well, even with trigging and all that..
