Goodbye Lullaby is the fourth studio album by
Canadian singer-songwriter
Avril Lavigne. It was released on 2 March 2011, being her last release under
RCA Records. The album was released four years after the release of her earlier album
The Best Damn Thing (2007), being pushed back several times. Recording sessions began in November 2008, and took place over a period of almost two years, concluding in October 2010. "Goodbye Lullaby" themes deal mainly with
heartbreak, exploring what it means to push through the tough times and emerge stronger for it, containing mainly stripped down instruments, such as the piano and acoustic guitar. Lavigne co-wrote every track on the album, with herself producing two songs alone. She also worked with producers
Max Martin,
Shellback,
Butch Walker and her former husband
Deryck Whibley.
