Duma

is a Nairobi-based duo formed in 2019 by Martin Khanja (Lord Spike Heart) and Sam Karugu. Combining grindcore, industrial, breakcore, and noise, they create an abrasive yet innovative sound that challenges genre boundaries. Their self-titled 2020 debut, released via Nyege Nyege Tapes, gained international acclaim and positioned them as pioneers in Africa’s experimental extreme music scene.
