It's less of an evolution and more of a "same spirit, different environs." Punk rock was the folk music of young, frustrated, white British kids and hip-hop was the folk music of young black New Yorkers. They both evolved fairly organically and had the same independent spirit. But I don't think Spoonie Gee was listening to Sham 69 records or anything...
Exactly my point.
And I agree that the Ramones started it all. Bitches.
