Los Angeles's The Dolemite Project have been colliding grindcore velocity with crossover thrash's d-beat swagger and classic thrash riffing since 2016, producing short, punishing songs designed to leave listeners winded.

In LA's vast and competitive underground, they've carved out a distinctive niche at the chaos end of the thrash spectrum.
