This is just a little tile in the mosaic of African American culture.
I don't agree that the African American sub culture is a matriarchy. In a typical inner-city environment, women having children out of wedlock and raising these kids with the help of an extended family is not an example of a household headed by a female wherein the male is subordinate to her rule. in these typical cases, the family unit is loosely structured and its members simply do whatever works, in some cases whatever works is a single man raising his kids in the absence of a responsible mother. In the black middle class, mothers and fathers typically share the household responsibilities and the raising their kids. In any case, an adult male member of a household routinely abandons the family rather than deferring to a matriarch. What is a more accurate description of the black family unit is that a "village" raises a child. It also should be noted that millions of single white women raise their children under these similar circumstances.
As for break dancing, Hispanics, specifically Puerto Ricans were an equal presence in its New York city origins. And, certainly, anybody who considers themselves as being aware of everything should be familiar with the abundance of pictures of old fashioned phonographs with turn tables.
@DelYour above response to pioneer's pontificating is right on point!
