Wasting Light is the seventh studio album by American alternative rock band Foo Fighters. It was released on April 12, 2011 on RCA Records. As frontman Dave Grohl wanted a record that would capture the essence of the band's earlier work and lack the artificiality of digital recording, the group recorded in Grohl's garage in Encino, California with only analog equipment. The sessions were supervised by producer Butch Vig, with whom Grohl had worked on Nirvana's Nevermind. Since the old equipment did not allow for many mistakes to be corrected in post-production, the band spent three weeks rehearsing the songs, and Vig had to relearn outdated editing techniques.
