1. Derek Roddy's Signature Licks — The gravity blast is one of the most specialised and widely studied techniques in extreme metal drumming — a method of generating extremely fast single-hand snare strokes by using the weight of the stick and the rebound of the drum head rather than muscular force alone. While the technique has been demonstrated and taught by several elite drummers, Derek Roddy is one of the clearest and most thorough teachers of its mechanics, having documented it across multiple Drumeo masterclasses and drum clinics where he breaks down the hand position, finger control, and body mechanics that make it work. His application of the gravity blast in the context of Hate Eternal's extreme-tempo compositions shows the technique at its most demanding: sustained, fast, and applied within musical passages rather than as an isolated showcase. The mechanics of the gravity blast begin with the stick held loosely in a fulcrum grip, raised to a set height and then dropped so gravity does the downstroke work. At the impact point with the drum head, the rebound energy is captured by the fingers, which redirect the stick upward to the original height before the process repeats. The key is that the muscles provide almost no downward force — they are used entirely for control and redirection, not propulsion. This means the technique is theoretically highly sustainable, because it does not tax the muscles in the same way that driven strokes do. In practice, the wrist and forearm still tire with extended playing, but the onset of fatigue is dramatically delayed compared to conventionally-driven single strokes. Applying the gravity blast within Hate Eternal's compositions requires not just mastering the isolated technique but integrating it into full kit playing — maintaining kick consistency and hi-hat control while the snare hand operates independently in this specialised motion. This integration is where most drummers struggle: the gravity blast feels natural in isolation but becomes unstable when the other limbs are working around it. Roddy's practice recommendation is to integrate slowly: gravity blast over a simple metronome pulse, then add the kick, then the hi-hat, building coordination before adding tempo. For drummers, the gravity blast is a genuinely transformative technique once it clicks — it opens up speeds that driven strokes cannot sustain, and it teaches economy of motion that improves every other aspect of your playing.2.
