Crossover thrash

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.

Since the 2000s, crossover thrash has experienced a number of underground revivals, which have produced notable acts including Municipal Waste, Trash Talk, Power Trip and Drain.
