this newly formed scene. Developments New York City would come to play a central role in the development of hardcore. In 1981 the Bad Brains moved from DC to New York and an important scene finally emerged, this is regarded a key point in NYHC as the Bad Brains had an enormous impact on local bands at the time. Besides the main influences of Bad Brains, Minor Threat and the Los Angeles punk scene; New Jersey horror punk band The Misfits as well as midwest groups Necros and especially Negative Approach are also regarded as early influences on the NYHC scene and the development of a rawer and more aggressive hardcore sound. Early NYHC skinhead bands like the Cro-Mags and Agnostic Front were also heavily influenced by Oi! music as well as English punk bands like The Clash. In the late-1980s, many clubs, namely CBGB began to refuse to book hardcore bands to perform, due to the increasing violence and gang behavior that was present at them. This also led many long time members of the scene to depart. Crossover period After the release of Metallica's 1983 debut album Kill 'Em All, New York hardcore bands began embracing elements of heavy metal music, especially thrash metal. This event caused the scene to expand, with the average attendance at shows jumping from around 100 to over 400. One of the earliest New York hardcore bands to embrace heavy metal influences was NYC Mayhem. In the following years many crossover thrash bands began to form within the scene, notably Leeway, Crumbsuckers and Nuclear Assault. New York metal bands like Anthrax and Carnivore began attending and performing at hardcore shows, and many original NYHC bands became increasingly heavier and harder in sound as the metal influences grew stronger, consequently some NYHC bands who were previously skinheads started growing their hair and adopting metal looks. Agnostic Front released the crossover album Cause for Alarm in 1986, which led many in the scene to deride them as sell outs. Writer Freddie Alva stated in a 2014 article that "[Cause for Alarm's] combination of heavy metal precision and hardcore energy created a landmark for the crossover sound". The Cro-Mags released the crossover album, Best Wishes in 1989, which also heavily impacted the scene. The album was cited as a major influence by much of the 1990s New York hardcore scene, particularly Biohazard, Merauder and Candiria. Youth
