Sure, their album sales are impressive but they are not that famous. If you ask someone who isnt an avid music fan and just tunes into daytime Radio One now and again chances are they arent going to have heard of The XX. The only time the price for a ticket should reach these heights is if they are either as mainstream as ice cream and everyone is desperate for a ticket or if theyre a band with a massive back catalogue on their comeback or greatest hits tour where no one has seen them for years. The XX, none of these. Theyre simply in that weird twilight zone between mainstream and underground where you do find a lot of good music about to break through, but pretentiousness runs high with the band being able to claim the props for being indie and the dollar for being mainstream.
