Sludge/grind

Sludge/grind is a variation of doom/grind that fuses blast beats with thick, sludgy guitars.

Characteristics
Sludge/grind differs from doom/grind in that rather than abruptly transitioning between grind and doom, songs generally consist of rapid drumming coupled with slow, thick guitars. The use of double blasts is also very common, often to emphasize vocal parts. Vocals are generally harsh, guttural growls and grunts.

Variations
Stoner/grind is a variation of sludge/grind that often uses stoner rock elements, such as flanging and phasing.
