Prophet – Shama, Shama. Gratitude.
John De’Mathew remains one of the most influential voices in Kikuyu Benga music, and for many fans, one sound instantly brings him to mind: “Seiyaaaaa!” More than a shout, it became his signature, an energetic call that signaled celebration, emotion, and connection with his audience.
The chant often appeared at the start or peak of his songs, hyping listeners and setting the tone for stories about love, social life, hardship, and everyday Kenyan experiences. “Seiyaaaaa” wasn’t just a performance trick; it was a way of pulling the crowd in, making every listener feel part of the moment.
Long after his passing, fans still echo the call at events, online clips, and tributes. It stands as proof of De’Mathew’s lasting impact, how a single word, delivered with passion, can become a cultural marker and a symbol of musical identity.
