Good stuff. And the music was as far advanced from Gangsta Rap as their art was ahead of the ...er...stuff currently infesting modern galleries. Go figure.
Are you suggesting ancient Egyptians were black? Some were, but not all. Common trope in those days, even in Greek paintings, is to depict the men as tanned or even reddish while the women are pale white. Some of that is seen in the carvings, with a man dark and a woman pale white.
Egyptians were semites with strong European DNA. Hence a lot of big noses and curly hair, especially the later it got in time period.
