Bob Marley performed in Harare, Zimbabwe in 1980 (Their Independence Day!) sparking a number of reggae performers in Africa.
Apartheid Not were one of those bands. They were a new wave/reggae/ska band from Nigeria. They released 2 albums and 2 singles (that I know of...there may be more)
Apartheid Not - African Rockers (1981)
3 No More War
5 Small Axe
6 Ega Nanoa Messi
Apartheid Not - Single Rescue (1982)
2 He Sends to Me
3 Life's Road
4 Leaving Us
5 All We Need is Peace
7 Should'n Should be Tired
8 Know Them
The two singles that I know of are the "Love Africa" 7" with Amama as the b-side. Both of those songs are on the Single Rescue album. Then there's the Listen 7" (b/w Listen instrumental) - I don't have that one.
