Mathcore


Mathcore is a rhythmically complex and dissonant style of metalcore. It was pioneered by bands such as Converge,Coalesce, Botch and the Dillinger Escape Plan. The term mathcore is suggested by analogy with math rock. Both math rock and mathcore make use of unusual time signatures. Math rock groups such as Slint, Don Caballero, Shellac, Drive Like Jehu and Dazzling Killmen have some influence on mathcore, though mathcore is more closely related to metalcore. Prominent mathcore groups have been associated with grindcore.

An early antecedent to mathcore was practiced by Black Flag, in 1984, with the album My War: "Its seven-minute metal dirges and fusion-style time signatures proved too much for many fans". Many groups from the mathcore scene paid tribute to Black Flag for the album Black on Black.

In the 1990s, groups now often described as mathcore were grouped together as "noisecore". Kevin Stewart-Panko of Terrorizer referred to groups such as Neurosis, Deadguy, Cave In, Today Is the Day, The Dillinger Escape Plan, Converge, Coalesce, Candiria, Botch, and Psyopus as described by this label. Stewart-Panko described the sound of these bands as a "dynamic, violent, discordant, technical, brutal, off-kilter, no rules mixture of hardcore, metal, prog, math rock, grind and jazz."
