Metalcore

Metalcore is a genre of musical fusion that incorporates elements of hardcore punk with other heavy metal. The term is an acronym for heavy metal and hardcore punk.

Apparently the term got its current meaning in the mid-1990s (to describe bands like Earth Crisis, Deadguy and Integrity), 2 the bases of the genre were established in the early 1989 with the work of Integrity.3 fusion of metal with hardcore had already existed years before in different forms, such as the thrash crossover with a greater influence of hardcore punk (also known as "old school" hardcore) 4 and the thrash metal of the late 1980s Metalcore differs from other fusions of punk metal by its emphasis on breakdowns: slow and intense parts that lead to the mosh.
