Martin Khanja, aka Lord Spike Heart, and Sam Karugu emerge from Nairobi's flourishing underground metal scene as former members of the bands Lust of a Dying Breed and Seeds of Datura. Together in 2019 they formed Duma (Darkness in kikuyu) with Karugu abandoning bass for production and guitars and Lord Spike Heart providing extreme vocals to the project. Their unique sound fuses the frenetic euphoria, unrelenting physicality and rebellious attitude of hardcore punk and trash metal with breakcore and raw, nihilist industrial noise through a claustrophobic vortex of visceral screams.
