I’ve been practicing my blast beats, of course. This is a video at 200 bpm, doing a blast beat with the snares off. Having the snares off gives me better rebound and it makes me feel better. I usually alternate between having them on and off. I think I used more fingers for this blast beat, especially for the left hand. I practice both wrist and fingers, but for higher speeds (which I still consider this to be) I tend to last longer using fingers.
