Extreme metal project Onsetcold have released their new single and accompanying music video, The Gates of Hell Are in Heaven.

Spanning nearly eight minutes, the track reworks material originally conceived for the 2020 Death Blast project, serving as a narrative prelude set 3,000 years in the past to the world of 2025’s Apocalyptic Sleep. The release follows previous experimental works including Art Destroyer and 2023’s Noam Chomsky.

Production on the single heavily incorporates unconventional methods, including converting MIDI keyboard arrangements directly to audio to replace standard guitar lines. Guest vocals on the track are provided by Seiza alongside project mastermind Shaq, who handled all instrumentation, recording, mixing, mastering, and the cover art oil painting The Death of Art.

The Gates of Hell Are in Heaven examines the human condition through a demonic lens, continuing the group’s blend of black metal, death metal, symphonic elements, and avant-garde structures.

The Gates of Hell Are in Heaven is out now via Wormholedeath.
