From Nairobi’s flourishing underground metal scene, we’re thrilled to host the unrelenting duo Duma. They’ll be performing alongside the primitive bad trip sludge punk of Birmingham’s Rainbow Grave. 




Duma fuse the frenetic euphoria and rebellious attitude of hardcore punk and trash metal with bone-crunching breakcore and raw, nihilist industrial noise through a claustrophobic vortex of visceral screams. Martin Khanja (aka Lord Spike Heart) and Sam Karugu are former members of the bands Lust of a Dying Breed and Seeds of Datura. Together in 2019 they formed Duma (Darkness in kikuyu) with Sam abandoning bass for production and guitars and Lord Spike Heart providing extreme vocals to the project.

Duma are a sinister force facing pain and difficult emotions head on. It’s a sonic aggression of feral intensity with disregard for styles. Their self-titled debut album was released August 7th 2020 on Nyege Nyege Tapes and has received the best accolades from the press, including best album in several end-of-the-year lists (Metal Hammer, Pitchfork, The Wire, The Quietus).


“extreme metal vocals, murkily distorted beats and creepy synthesised atmos”
The Quietus





Rainbow Grave play bleak mantras that channel the blank despair of negative punk through layers of distorted psychedelic damage. Expect freeform pedal abuse and robotic vocals coagulating around cyclic bass and drum rhythms in repetitive and minimal structures. Recordings are available from the God Unknown label, including the album ‘No You’ (2019). Disappointment guaranteed from these members of Napalm Death, Scorn, Doom & Sore Throad.


“The grindingly bleak sound of well fed disgust and smothering disenchantment.”
