Adenaike is a watercolorist of Yoruba heritage and has a passion for Igbo symbols and culture. He received a BA in Fine Art from the University of Nigeria, Adenaike in 1979, and a MFA in Painting in 1982. After graduating, he has worked in advertising and graphic design.

Adenaike is considered by art historians and critics as a third generation artist of the Nsukka School, pioneered by Uche Okeke, Chike Aniakor and Obiora Udechukwu. The School is closely associated with Igbo traditional art and wall paintings known as uli, which formed the foundation of the School’s creative experimentation.
