I call bullshit on this entire video because there is no right or wrong way to approach any instrument.
If I want to listen to drummers who all sound the same, I'll check out the modern death metal scene full of polished production and everyone doing the same blasts and grinds with no originality, innovation or personality allowed to come through in their music.
Some of the worst drummers and musicians I've ever heard have got some brilliant ideas and personalities in their playing, and that's something that should be followed up rather than turning your playing into a copy of everyone else so that you can say you're doing that blast "correctly."
Has this guy never listened to Immolation? The drumming on failures for gods is so spastic, uncontrolled, uninhibited and all over the place, and by this guy's ideals "wrong" or "incorrect" but it has soul and character.
