Crossover thrash is a fusion genre of thrash metal and hardcore punk. The genre emerged in the mid-1980s, when hardcore punk bands, such as Suicidal Tendencies, Cryptic Slaughter, Corrosion of Conformity and Dirty Rotten Imbeciles, began to incorporate the influence of thrash metal. At this time, the genre was particularly prominent in the New York hardcore scene, where groups including Agnostic Front, Leeway, Cro-Mags and Stormtroopers of Death were widely influential.
