I learned about these guys last year after having a convo with a friend who was just getting into making rock himself.
Brehs from NY in the 70's
WITCH (We Intend To Cause Havoc) - came out in the 70's - they are from Zambia
Ngozi Family - another band from Zambia
This one - I have a roundabout personal attachment to - my Uncle went to school with the guitarist, in Ghana. The band ended up hanging with Fela in Nigeria and playing at his spot, The Shrine.
Learned about these guys on here - I believe they band members were all from the Carribbean, but met in the UK
These guys predated The Ramones and some people credit them with being one of the earliest punk groups. There's a really good doc out there about them. The sons of two of the members actually have their own rock group now called Rough Francis
