A blast beat is a rum beat, primarily used in forms of extreme metal, made with rapid alternating or coinciding strokes primarily on the bass and snare drum. Diverse patterns and timings are also frequently used by more technical players, such as Gene Hoglan (Strapping Young Lad/Dark Angel), Alex Hernandez (Immolation), or Flo Mounier (Cryptopsy). Alternative styles of blast beats include using a two strokes on bass drum followed by one stroke of the snare drum, such as played by Pete Sandoval (Terrorizer, Morbid Angel), or using scarce strokes on the bass drum, which are frequently played by Max Duhamel (Kataklysm).
