Guided by Voices is a top notch band with a rough touch sound. Some of the roughest recordings by any band as good as they are, Lo-Fi is definately a overstatement of their sound. But it's one of the things that makes Guided by Voices so fucking cool. Well, that and the fact that despite the fidelity they manage to write some of the catchiest fucking songs imaginable. They're broken up now but I urge you to check out Earthquake Glue or Alien Lanes, amongst others.
