The beat of explosion.

This is a video.
Other barrels involve many metals.
Excuse me. . I can't watch that video now. .
If it's George W. snare drum's quick hit, it's the blast beat.
If the bottom drum is particularly fast, the small drum is very uniform. . It's like an eighth note on the hand and a thirty-two note on the foot. . . It's just an ordinary two-step rhythm. . . There is no specific name. .
