HEAVY HALLOWEEN
Saturday, October 31, 2026 - The Underworld, London
Heavy Halloween brings a stacked metal bill to The Underworld on 31 October 2026, headed by Inhuman Nature, whose crossover thrash and thrash metal drive the night. They are joined by Puppy, Agnosy, Asidhara and Hanowar, making this the sole Heavy Halloween date. With Inhuman Nature’s thrash attack sitting alongside Asidhara’s metal and the rest of the line-up, the show leans hard into riffs and high-intensity volume in a compact Camden basement space. For anyone tracking heavy gigs at The Underworld, this one-off Halloween performance pulls several strands of metal into a single bill.
