I guess I should preface by saying I've never really liked their music. The bendy guitars and noisy dissonance is generally just unappealing to me, and his vocals are the final nail in the coffin. I can listen to a lot of similar noise rock, but something about their whole aesthetic, especially live, has always been a turn off.
But, I have an idea that it wasn't all my personal bias. There was a couple beside me, mid/early twenties, who were going NUTS before their set. They were so excited. By about 5 songs in, you could tell the disappointment was settling in and they reacted less and less and less. Then they didn't play Float On. Who do they think they are? Radiohead?
