PITTSBURGH, PA — The underground rises once again. Descendants of Crom VII returns to Thunderbird Café & Music Hall on September 26–27, 2025, bringing two nights of genre-defying heavy music, collaborative creativity, and the raw energy of Pittsburgh’s thriving DIY spirit. Now in its seventh year, DOC continues to grow in scope and reputation, while staying fiercely committed to underground authenticity.
Presented by Blackseed Services in collaboration with Thunderbird Café, this year’s festival features an unmissable lineup, including sludge juggernauts BLACK TUSK, the epic intensity of VALKYRIE, doom torchbearers CRYPT SERMON, and Cleveland hardcore legends RINGWORM. Supporting acts span a range of sonic extremes: FISTULA, CHERUBS, SATHANAS, WEED DEMON, REBREATHER, EDHOCHULI, OLATHIA, FUNERALS (formerly Horehound), BROWN ANGEL, RIPARIAN, FOG GIANT, and PASSING BELL.
DOC isn’t just a lineup—it’s an experience. From custom-brewed beer and small-batch hot sauce collabs to themed vendor offerings and exclusive merch, the weekend celebrates the underground in all its forms. Blackseed Services has spent over a decade cultivating Pittsburgh’s heavy music culture by consistently showcasing unique artists—many of whom fans wouldn’t otherwise get to see locally—while lifting up the city’s own talent.
With a focus on genre inclusiveness, artist integrity, and authentic community building, DOC is where longtime followers of the riff meet new initiates. Fans come for a favorite band and leave with a deeper connection to a movement—and often, a few new obsessions.
