Drones is the seventh studio album by English rock band Muse, released on 5 June 2015 through Warner Bros. Records and the band's own Helium-3 imprint. The album was recorded between October 2014 and April 2015 at the Warehouse Studio in Vancouver, with orchestral sections recorded at Officine Meccaniche in Milan, and was produced by the band and Robert John "Mutt" Lange. Drones is a concept album following a soldier's abandonment, indoctrination as a "human drone", and eventual defection. It also comments on the Obama administration's drone program. After their previous albums incorporated orchestral and electronic music, Muse aimed to return to a more straightforward rock sound musically.
