Mathcore

Mathcore (or experimental metalcore) is a genre of music often seen as a subgenre of metalcore that combines the speed and aggression of hardcore punk and extreme metal. The genres roots can also be traced to post-hardcore and math rock bands of the early 1990s. Bands in the genre emphasizes complex and fluctuant rhythms through the use of irregular time signatures, polymeters, syncopations and tempo changes. Early mathcore lyrics were addressed from a realistic worldview and with a pessimistic, defiant, resentful or sarcastic point of view. In the 1990s, the hardcore punk scene started to embrace extreme metal openly and also was highly ideologized, with most of the popular bands being part of subcultures, leading to bands such as Converge, Botch, Coalesce and The Dillinger Escape Plan to establish the genre (which at the time was known as noisecore).
