Hardcore punk

Hardcore punk is a musical subgenre derived from punk rock which originated in the United States and later in the United Kingdom in the late 1970s. It is characterized by being the evolution of the most energetic aspects of punk: the tempos and measures are very fast, the drum rhythms very fast and aggressive (usually 180 to 200 beats per minute), the guitar lines played quickly and sparsely arranged, amplified, and distorted, electric bass typically doubles guitar chords (nonscale, occasionally octaves), the voice is nearly shouting, fast, and songs are often short. Various genres have emerged from hardcore, sometimes merging with electronic music, rap, metal, deriving subgenres such as melodic hardcore, post-hardcore, hardcore beatdown, metalcore, mathcore, deathcore, grindcore, grunge and many others.
