Caught them near the end at the O2 in Birmingham, I have to be honest that it was among the worst live sound I've ever heard, but that was mostly down to the room acoustics and I suspect the engineer wasn't doing his best work - but basically the room ambience was so bad, and the bass so strange sounding, that you couldn't actually latch on to what key the songs were in with your ears. Strangest aural experience I've ever had!
Frustrating, because you could tell they were killing it on stage.
