Nothing says 'watch out for our new album' quite like a tweet from legendary boxer, Mike Tyson... That is exactly how American rockers, The Black Keys, decided to announce their latest musical offering. Yesterday Tyson tweeted a message that simply read, "Turn Blue", followed by a link to an unusual YouTube video that turns out to be the duo's new teaser clip for the record.

  The album title explains drummer Patrick Carney's behaviour on Instagram. Carney has been posted blue tinted images over the last few days, not to mention uploaded a screenshot of boxer pal, Tyson's, message. The record will hit shelves May 13th and you can watch the promo here: https://www.youtube.com/watch?v=Zq40vTdaa2w
