About This Event
Mastodon headlines a concert at the Fillmore Auditorium in Denver with support from Deafheaven and Alcest as part of their North American 'Poisonous Weapons' tour. The bill pairs Mastodon’s progressive/metal sound with Deafheaven and Alcest’s blackgaze and post‑black metal approaches, making it a notable night for fans of heavy and experimental metal. The tour follows the band’s recent return with the single “Your Ghost Again,” which music outlets describe as a tribute to the band’s late guitarist.
