Old Man Gloom, SubRosa Reunion, Full Of Hell & More Added To 2026 ‘Fire In The Mountains’ Festival

The 2026 edition of Fire In The Mountains continues to take shape, with festival organizers unveiling another stacked wave of artists — including a long-anticipated reunion from doom metal favorites SubRosa.

Salt Lake City’s SubRosa, who disbanded in 2019, will reunite for a special performance at the festival. Also newly confirmed is post-metal supergroup Old Man Gloom, featuring members of Isis, Converge, Cave In, and more, marking another rare live appearance for the band.

Additional announcements include grindcore extremists Full Of Hell, a collaborative performance between Iggor Cavalera (Cavalera, ex-Sepultura) and acclaimed Navajo/Diné composer Raven Chacon, as well as sets from Yaotl Mictlan, Savage Oath, and El Welk.

The 2026 Fire In The Mountains festival is scheduled for July 23–26 and will once again take place at Red Eagle Campground in East Glacier, Montana, with the event continuing its tradition of blending extreme music, cultural reverence, and immersive natural surroundings.
