I will probably get tomatoes thrown at me here...
I was at their show in Chicago and didnt like it. I was seriously falling asleep there (having slept about 3 hours the previous night might have had something to do with that as well).
I wasn't really familiar with their stuff before seeing them, but i've heard them being compared to Mogwai (which i like a lot). The vocals are way over the top and their whole sound is just too weird for me.
Now i might not be a musical expert, but i failed to hear any sound produced by the guitarist, who seemed to play his guitar so vigorously with a cello bow. And correct me if i'm wrong, but i think the strings on a guitar are arranged in a straight line, as opposed to an arc in classical string instruments, so touching individual strings with a bow is somewhat complicated.
