Sonny Okosun was a Nigerian musician, who was known as the leader of the Ozzidi band. He named his band Ozzidi after a renowned Ijaw river god, but to Okosun the meaning was "there is a message". His surname is sometimes spelled Okosuns and his first name Sunny. He was one of the leading Nigerian musicians from the late 1970s to mid-1980s.
Okosun's brand of African pop music, Ozzidi, is a synthesis of Afro-beat, reggae and funk music. From 1977, he became known for protest songs about Pan-Africanism, freedom and a few other social and political issues affecting Africans.
