A Domino rep went to a listening party in Norway where the album was played. I was told the album was indeed a concept, but that it sounded "a lot like an Arctic Monkeys album". No single release date has been published internally at Domino, but that doesn't mean there can't be a surprise single release. It's not like they need PR in advance to get the hype going.
But there is going to be a "special thing" being released ahead of the album but I don't know what it actually is, or if it's single, tour announcement or something completely different. Stay tuned!
