"The Hygrades were the creation of Enugu-based guitarist and producer Goddy Oku. They released a string of 45s for HMV/EMI in the early 70s including the tracks Keep On Moving, Somebodys Gonna Lose or Win, Rough Rider & Jumping Cat. Oku was a very talented musician and his bluesy rock-guitar licks got a chance to shine on the instrumental sides of all the 45s. He had a reputation as a technical genius, always building sound equipment, amps and even his own guitars. He still runs his Godiac studio in Enugu in the east of Nigeria."
