This gives me the perfect excuse to promote some South African bands

First off, my friends:
Strident, some power metal insanity.

And some more friends:
A Walk With the Wicked, death metal. The quality isn't brilliant, but these guys are seriously good.

aKING, one of the country's bestest rock bands.

And now, for something completely different:
Tonik, grassroots/instrumental/percussion/whatever. A band I only recently discovered. They're currently touring in Germany and Switzerland, actually. I'm actually in that montage, heh.

Lark. Electronic weirdness. They've disbanded, sadly.
