Moshcore is a style of metalcore, derived from hardcore featuring guitar-based instrumentation, basic chord progressions, aggressive 4/4 rhythms and assertive vocals. It is also known as Tough Guy Hardcore. Distortion is usually introduced into the guitar sounds, which can create a heavy metal effect that further sets moshcore apart from punk rock. Moshcore is created and played mostly for mosh dancing in a “mosh pit”, which can be a violent activity involving high impact body contact (and some physical risk). The style emerged during the late 1990s in Germany and the northeastern United States. It is stylistically different from the punk subgenre of “Hardcore”, and is generally “heavier” than punk hardcore, but often employs a much “friendlier” and much less abrasive musical style than other Hardcore subgenres, like Crust.
