I am not saying this just because I used to live there, but I think South African black people are highly creative in blending their own cultures with others and turning them into something new and better.
Take for example South African Jazz and Pop music. The most famous in the US may be Hugh Masekela, Abdullah Ibrahim and Miriam Makeba. My favorites are Sakhile, Bayete, Stimela and Sankomota. I am also a big fan of Lucky Dube, who has been leading South African Reggae scenes. These artists are common in that they have blended conventional Jazz, Pop, R&B, and Reggae music with traditional South African music and rhythms; and created something so unique and distinctive as South African. At the same time, they have conveyed their political messages through their songs, which were born out of the context of anti-Apartheid movements.
Since Mandela was released from the Robben Island, South African music has undergone some changes, particularly in its "messages" that they convey, though its blending of different cultures has continued. For example, Kwaito, a mixture of house, hip hop and traditional rhythms originated in Johannesburg in 1990's, talks more about apolitical stuff and gears more towards empowerment and integration as well as "street" issues, reflecting contemporary (post-Mandela) South African social realities. Artists like TKZee and Bongo Muffin have got really cool vibes.
By the way, when I was writing this post, I came across a news piece from BBC in 2003 about a group of white supremacists held in a prison in Pretoria, South Africa. They were apparently complaining about loud Kwaito music played all day long in the prison, claiming that they were "tortured." Remember - these guys were the ones who had perpetrated all types of violence against South African black populations!!
