The music of Nigeria’s reclusive synth funk innovator William Onyeabor has reached a new level of exposure via Luaka Bop’s excellent Who Is William Onyeabor? compilation last year, yet many hard facts about Onyeabor’s biography remain elusive. In their new documentary “Fantastic Man,” Noisey speaks with musicians and champions of Onyeabor’s music, including our own Quinton Scott and Duncan Brooker who included the sublime “Better Change Your Mind” on the first Nigeria 70 compilation, about their appreciation for his music, and the search for the facts about his life.
