Progressive metalcore


Mathcore is a dissonant fusion of heavy metal and hardcore punk characterized by unusual time signatures, experimentation, and rhythmic complexity. The genre has been shaped primarily by math rock and metalcore. The term mathcore is a portmanteau of the terms math rock and hardcore. The fusion has also been referred to as noisecore and experimental metalcore. Prominent mathcore groups have been influenced by free jazz,noise rock, and grindcore.

Mathcore was pioneered by bands such as Converge,Coalesce, Botch, and The Dillinger Escape Plan.

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 commonly called "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 falling under 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."
