Gravel Trestle Groan

Frames jump between jagged, overdriven shapes, so the tone keeps skidding from a low growl into sharper tearing upper partials. Motion across the scan is restless rather than smooth, neighbours snapping to new shapes instead of easing into them. Best as short bursts or layered under distortion.
