If you like dissonant, slightly chaotic music, Arab on Radar is a band you should check out. Somewhere between the noisey guitar driven Jesus Lizard and straight up 'art rock', they are a really fun band to listen to. It may take a little getting used to, but once you get past the abrasiveness of it all, there are some really interesting things going, especially if you're a musician. Check out their myspace page to get a feel:Arab on Radar. Also check out the other bands on Skin Graft Records.
