Joseph Kamaru (KMRU), is a sound artist, and producer based in Nairobi. He is notable for making intelligent atmospheric and emotionally experimental music, giving a personal touch using everything from gritty indigenous sounds to field recordings and synthesis to creat intricate sonic soundscapes.

KMRU is also a DJ, and his mixes share a similar philosophy, where the music often has an elegiac quality of sounds, Foleys and field recordings, sometimes accompanied with a pulsing slice of atmospheric techno suggesting a more cinematic approach.
