Mind y'all, I don't have any confirmation on this... but it looks pretty certain, as their name's not on the site.
And I didn't necessarily mean "gimmick" as negative. I too have been cranking some $O$. But, honestly, no one would know who they are based solely on mic skills and production. It's all about how exotic Dutch and American folk find Afrikaans swearing and trash culture. Back in SA, they were still playing tiny shows. From what I gather from friends there, Fokofpolisiekar are and were infinitely more popular (although, granted, that's another genre).
Let's just hope Ninja and Co. pull through the DMV some time, preferably with Jack Parow opening.
