I'm not South African and i don't really know most of the S.A rock bands. I watch Mk89 on DStv so i've seen some of the videos and i think quite a lot of the band and i like some of them.
Some really good band in my opinion include Prime circle, cutting jade, the finkelsteins, and parlotones. I don't a lot of their song just the popular ones with the videos, but i'll be going to university in S.A in 2008 so i'll get more exposure of the bands.
I also like that afrikaans track by the band called K.O.B.U.S.I, i think its called "Swaarsmetaal"(not sure) no idea what they're saying but i love it anyway.
