What makes Nigeria 70 particularly compelling is its sonic diversity. Anyone expecting two and a half hours of music that sounds directly informed by Fela might be surprised to find out just how many musicians saw his music as a starting point than the sum of their sound. There's nods to psychedelic rock, both heavily fuzzed-out (Ofo & the Black Company's stomping, wailing "Allah Wakbarr") and Deadhead-friendly mellow (BLO's eerily beautiful reverie "Chant to Mother Earth"). A few forays into the late 1970s and early 80s note a disco influence that informs cuts like Joni Haastrup's 1977 song "Greetings" and Shina Williams & His African Percussionists' 1984 electro-funk workout "Agboju Logun" without removing their Afrobeat backbone. And if you're wondering how Parliament-Funkadelic was received in Nigeria, William Onyeabor's 1978 anti-imperialist synthesizer opus "Better Change Your Mind" is an intriguing hint. You could while away some time trying to figure out just how much or how little of it came from black music in America, and how much of black music in America actually owed to these sounds in the first place— as cross-cultural development of pop music goes, the Nigerian sound is fascinatingly tangled. And now, even after the West African reissue glut of 2008, Nigeria 70 still sounds illuminating.
