"The nine tracks on this years-in-the-making compilation feature music drenched in analog synths, early drum machine sounds, and wah-wah, phase-shifted guitars and basses. It is all seductive, infectious, and timeless. On set-opener "Body and Soul," Onyeabor co-opts tranced-out, Nigerian juju music, saturates it in slow Afro-funk, and weds it all to P-Funk's call-and-response lyric and chorus; after ten minutes, the effect is consciousness altering ... Who Is William Onyeabor? may not answer many biographical questions, but it does paint a superb portrait of the musician as a highly original creator and pioneer; it adds depth and dimension to the picture we have of African music during the era".
