The Gates of Slumber, hailing from Indianapolis, Indiana, emerged as a relentless force in the doom metal scene with their inception in the late 1990s. Founded by vocalist and guitarist Karl Simon, the band has become synonymous with the resurrection and evolution of traditional doom metal, marked by its heavy, melancholic riffs, and epic storytelling. The band’s sound pays homage to the forebears of the genre like Black Sabbath while infusing their own unique and often morose thematic elements.

Through a series of powerful albums and singles, including notable releases such as "The Wretch," "Hymns of Blood and Thunder," and "The Awakening," The Gates of Slumber has distinguished itself with compelling compositions that hearken back to the genre’s roots, characterized by sludgy, slow-burning guitar work, and haunting vocals. Their music often explores dark and fantastical themes, a fitting accompaniment to their thunderous and brooding sound. Despite undergoing several lineup changes and facing the tragic passing of their bassist Jason McCash in 2014, The Gates of Slumber's legacy endures in the doom metal subculture, solidifying their status as torchbearers of a genre that worships at the altar of the riff.
