April 30 to May 3, 2026, at OC Molenhuis in Molenstede (Diest)

The indoor metal festival Hell On Air proudly announces the full lineup for its 2026 edition. With the addition of the explosive American metal duo KrashKarma, the three-day program is now complete.

The festival takes place from April 30 to May 3, 2026, at OC Molenhuis in Molenstede (Diest) and promises to be one of the most intense metal events of the year.
OC MOLENHUIS, Dorpsstraat 47, Molenstede (Diest/Belgium).

Hell On Air brings a mix of international and national metal acts, including Liv Sin, Temtris, KrashKarma, and other explosive names that will fill the weekend with heavy riffs and pure energy. The festival is known for its powerful atmosphere, strong programming, and close ties to the metal community.

“With KrashKarma joining us, the lineup is complete and stronger than ever,” says organizer Erik. “Hell On Air is built on passion, fire, and connection, and this edition will undoubtedly be our most explosive yet.”

KrashKarma, the unique two-headed metal monster from Los Angeles, is known for their brutal energy, dual vocal power, and live shows that feel like a controlled explosion. Their arrival gives Hell On Air an extra international punch.

Belgian death metal legend Exoto, who died a few years ago, was persuaded to play one last show at Hell On Air. Not to be missed, just like the other 29 bands on the bill.

With the final of the Alcatraz Bash on Friday and a selection of Belgian bands on the bill, Hell On Air also gives homegrown talent a chance to perform.
