Check out Djembefitta, a new thrash-punk/crossover act from Göteborg that prides themselves on being anti-everything usually associated with Gbg music: http://www.myspace.com/djembefitta
Their manifesto: "Our aim is to kill pop music from Gothenburg where every band has a singer that sings out of tune. Håkan Hellström/Bad Cash Quartet/Hästpojken/Broder Daniel/Jens Lekman/Niccokick (well they live close enough to Gothenburg to count) et al are so terrible but everybody loves them... Isn't that strange?"
