UK arena rockers Muse will release their seventh full-length Drones in June 2015 on Warner Bros. Records. Co-produced by Muse and Robert John "Mutt" Lange, the album contains 12 tracks and is preceded by lead single "Dead Inside." Frontman Matt Bellamy explains the album's themes, "To me, 'Drones' are metaphorical psychopaths which enable psychopathic behavior with no recourse. The world is run by Drones utilizing Drones to turn us all into Drones. Drones explores the journey of a human, from their abandonment and loss of hope, to their indoctrination by the system to be a human drone, to their eventual defection from their oppressors." Muse have sold 17 million albums worldwide. Their last album The 2nd Law was released in October 2012 and topped the charts in 21 countries including the UK.
