This page contains material about extreme drumming. Also known as Blast Beats or Skunk. This involves playing at high speeds, often in excess of 250 and up to 300 bpm. This type of playing is used mostly in metal playing. It can be useful, however, to improve your stamina/endurance and speed in general.
