Arctic Monkeys Album Teaser

Arctic Monkeys have shocked everyone by releasing a new short song seemingly the second they've finished recording it in California with no explanation or clues as to when their new album will be out.
So apart from the surprise of the shock release what's the song actually like? Well reviews have been mixed and fans appear to be split with some ecstatic and others thoroughly nonplussed. One of the word that keeps popping up when this song is described is change and it's true this track is a million miles away from their first influential and no nonsense album. Instead of the clear thrashing drums, powerful bass and intricate lyrics which defined their earlier work it's now distorted, fuzzy, simplistic and reminiscent of the 70's. They no longer sound like the monumental band that came from no where and ruled the rock scene with their witty lyrics and simple riffs but now more like the long gone rock elite.
Some will celebrate this change in direction as it shows that they're evolving as a band and not resting on their laurels and I agree that it's important to grow as a band. Others will say that this change is a loss as through their development as a band they've lost what it was that made them so great and I regrettably have to agree as well. I don't dislike this song and found that it grows on you the more you listen to it but when compared to their old material it just feels like something is missing. 
 I'll be eagerly awaiting the release of more material to see whether they have successfully managed to keep the essence of what makes them great whilst simultaneously developing.
