Crossover thrash is a music genre that blends elements of thrash metal and hardcore punk. It emerged in the 1980s, characterized by fast tempos, aggressive guitar riffs, and shouted vocals. Bands often incorporate the raw energy of punk with the technical precision of metal, creating a unique sound that appeals to fans of both genres. Notable bands in the crossover thrash scene include Suicidal Tendencies, D.R.I., and Municipal Waste. The genre is known for its energetic live performances and often addresses social and political issues in its lyrics. Crossover thrash remains influential in both the punk and metal communities today.
