'The included DVD is a record of the concert - and is a tad arty farty to be honest'
I am yet to see the DVD (order from Amazon dispatched today) but I already know that I'll be agreeing with your viewpoint. The reason?: Mr Vincent Moon, who has the remarkable ability to make any music film overly arty (see recent efforts pertaining to Mogwai & The National). I personally love seeing an artistic vision and am by no means a philistine but Vincent Moon is one of my most hated film makers around, he seems to suck all the life out of any given project and instill it with various 'oh-so-clever-look-at-me' style shots & colour schemes.
For an example as to how art can be applied to a music video, take a look at the recent Animal Collective DVD 'Oddsac'. Director Danny Perez infuses the music with wonderous visuals to create a dramatic and intoxicating head****.
