Nice read, thanks for posting. I grew up in Zambia in the 80s I and live in SF now, and I never heard of Zamrock before.
This comment about young Zambians - "They marvel when they listen to Zamrock. They think Zambians could not have done that." - saddened me. It seems to apply to a lot of areas of life there now. There used to be a time when Zambians were self reliant, growing their own food and making their own goods, but now everything comes from South Africa and most Zambians are just consumers.
