The Null Device
The Grauniad has a piece on the heavy metal scene in Botswana, which combines the music and aesthetics of metal as we know it with local influences (cowboy hats, it seems, are big among Kalahari metalheads):
Dressed from head to toe in black leather, sporting cowboy boots, hats and exaggerated props, they draw some curious looks on the dusty streets. "People think that we are rough, evil creatures, but [metal] teaches us to be free with expression, to do things on our own," said Vulture, the vocalist of the band Overthrust. He says there is a long way to go before the genre is considered mainstream, but that audiences have grown steadily in the past decade.
Though attendance at concerts is small in comparison to the west, the scene has slowly built a steady fan base. To date, no western heavy metal act has performed in Botswana, and no Botswana metal act has performed outside the region.And there are photos of some Batswana metal dudes, with sobriquets like Death, Warmaster and Maximum, here. I imagine wearing all that black leather in the Kalahari heat must be an even greater peacock-tail signal of commitment than being a Goth in Brisbane.
