Intrigue was immediately triggered when hearing the word ‘grindcore’ associated with this Nairobi duo. Martin Khanja (aka Lord Spike Heart) and Sam Kurugu are both veterans of the city’s underground metal scene and the way their eponymous album (Nyeye Nyege Tapes, 2020) merges extreme noise terror with the tools of the electronic dancefloor is like a glorious trepanning that opens the mind to all manner of previously hidden avenues of thought and feeling. Duma are getting a lot of attention right now and will no doubt be touring heavily in Europe come the return of normality. A culture clash in all the right ways, dissolving expectations and scorching ear canals. Oh, and Duma means Darkness. Metal to the core.
