There is more than one artist under this name:

1. KAMAU
Marcus Vinicius Andrade e Silva, better known by his stage name Kamau, is a Brazilian rapper, composer, beatmaker, producer and skateboarder. He began his career in 1997 and is seen as a reference by many of the MCs currently standing out in the scene and also admired by veterans.

2. KAMAU
KAMAU Mbonisi Kwame Agyeman—which literally means quiet warrior, affectionately called, little brother by his father, has always been a passionate and creative soul.
His path in life seemed to be almost certain from birth.
As a child KAMAU was very original and slightly unorthodox. Little brother was known to be always friendly with a wacky, witty sense of humor; deeply meditative, and possessing a strong sense of intellectual independence.
Ironically, the beautiful, odd and abstract sounds of gibberish we hear in KAMAU’s music, was at times, a source of parental irritation, at least around the dinner table.
