Celebrating 25 Years of Darkest Hour. Washington, DC’s DARKEST HOUR combine the passion, energy, and soul of punk/hardcore with the style, speed, vengeance and fury of melodic speed, thrash and death metal. They've helped define the entire new wave of American metal sound as one of the pioneers of modern metal/core. A sound that gave the metal and hardcore/punk world the revitalization it surely needed. This style blended the raw, hardcore punk of the 80s, with the Scandinavian death metal of the 90s and forged a sound that would later become the template for modern metal.
