Brothers is the sixth studio album by American rock duo the Black Keys, released on May 18, 2010, through Nonesuch Records. It served as the follow-up to Attack & Release (2008), the band's first professionally-recorded and non-self-produced studio album. Brothers was largely produced by the band alongside Mark Neill, with the exception of "Tighten Up" produced by Danger Mouse. The album was recorded in late 2009 at Muscle Shoals Sound Studio in Sheffield, Alabama, Neill's Soil of the South studio in La Mesa, California, the Black Keys' home studio in Akron, Ohio, and the Bunker on Apple in Portland, Oregon.
