The world's loudest craft beer festival returns—national metal brewery pours (3 Floyds, Surly, Odell, Left Hand, Ratio, and more) paired with stacked metal lineups at the Fillmore across two crushing nights. Daily schedule / notes: Exact door/session hours not on overview page—confirm from ticket links before create. Listing uses conservative afternoon–late window spanning both days (within 5-day cap). Optional pre-fest Dec 3 at Ratio.
