Rävjunk

This raw Swedish progg-punk band, whose name, delightfully enough, means "fox piss" in English, got their start back in 1970, a bunch of teenagers drinking beer and jamming and doing the occasional Black Sabbath or Jimi Hendrix cover. As they got a little more serious, they wrote more original songs, but jamming remained a big thing with them. They were part of the Swedish underground music scene in the '70s, playing the summer free festivals and hanging with freaks and anarchists and so forth. Read more on Last.fm
