Lágbájá

Biaade Ologunde, Nigerian Afrobeat musician, singer, and percussionist adopted the name Lágbájá (meaning "Jane Doe" or "John Doe"- A person whose name, identity is intentionally concealed in Yoruba) as he embarked on his career in the early 90s.

His name was reflected in his choice of stage attire – a slitted textile and rubber mask adopted so that the artist represented the ‘common man’ in keeping with the carnival tradition of his Yoruba tribe.
