OH GOD, TRENDING FASHION. TEN MINUTE ZEITGEIST. QUICK, RIDE THE WAVE WHILST IT'S COOL.
I was in South Africa back in 2002, and you could buy these damn things everywhere, but in light of the world cup, they've become wildly popular. I think they resonate with exactly what the world cup seems to be about- a gigantically dumb and unsubtle spectacle with a carnival-esque atmosphere. I should point out, I don't neccesarily consider that a bad thing.
However, someone's set up a twitter for the vuvuzela, which just prints random humming noises every couple of hours, and I've come across two vuvuzela influenced tunes. If there are more, just post a link below. This thing is trending like crazy, and will be dead within a few days, but for now...
London producer "DJ Total Confucious" (thanks to Joe Muggs for the link) came up with a rave /vuvuzela tune with an awesome video.
The other's a free download from soundcloud from Mr. Benn, and is far more ragga-carnival. fun. Mr Benn - Vuvuzela riddim by Mr Benn
