Yolandi Visser (stylized as Vi$$er), is best known as a rapper in the South African rap-rave group Die Antwoord.

The band self-identifies as a melange of several diverse cultures all mixed into one.

Die Antwoord identifies their style as “Zef” music, Zef being an Afrikaans term which loosely translates to the culture of working class white South Africans, especially those residing in Cape Town.
