In 2018, a group called Sailors released "Wamlambez" from a studio in Nairobi's Eastlands. The song was crude, infectious, and recorded for almost nothing. Within weeks, it had millions of streams. Parliament condemned it. Radio stations banned it. Then President Uhuru Kenyatta played it at a State House event. Gengetone was born in estates where kids had smartphones but no jobs, and it became the sound of a generation that refused to wait for permission to be heard.
