Lets get this right. Do not think of this as the Arctic Monkeys live, (even though it is!) think of it more as.. the Arctic Monkeys just playing their songs.
For a start, they don't really move at all on stage, don't really talk to the crowd, they act like they don't want to be there (especially Alex) and there is NO atmosphere. Let me repeat that last part because I have to stress that there is absolutely no atmosphere whatsoever! They have been recorded so that the noise of the crowd has been cut out although not over dubbed but recorded so it just sounds like its 4 guys in a room with no audience or anyone else there apart from the odd moment of screams between songs.
Singing and playing is perfect but like I said it's very boring to watch.
