Joseph Kamaru (born 1938 in Kangema, Murang'a County, and died in 2018 at age 79 in Nairobi) was a highly influential Kenyan musician, political activist, and cultural icon, widely regarded as a pioneer of modern Kikuyu music. After moving to Nairobi in 1957, he pursued his interest in music and purchased a guitar with his savings, leading to his breakthrough with the release of songs such as “Ndari ya Mwalimu” in 1966 and "Celina" in 1967. Kamaru revolutionized traditional Kikuyu folk music by incorporating Benga rhythms, creating a distinctive sound and a catalog estimated to contain over 1,000 songs across both secular and gospel genres. Known for his strong storytelling and cultural commentary, many of his songs were politically motivated, either praising or criticizing the government, and he enjoyed access to Kenya's political leadership, performing at state events and cultural tours. In the 1990s, he transitioned to gospel music, disbanding his former group, the Kamaru Supersounds. He is remembered as a mentor to younger artists, having established a Nairobi studio to support upcoming musicians, and for selling about half a million records during his career.
