Avril Lavigne is the self-titled fifth studio album by Canadian recording artist Avril Lavigne, released on 1 November 2013 by Sony Music Entertainment. The album is a follow-up to her 2011 effort Goodbye Lullaby and was developed shortly after its release. Lavigne collaborated with numerous producers including Martin Johnson, Peter Svensson, David Hodges, Matt Squire and her then-partner Chad Kroeger. In both musical and lyrical aspects, the album represents a departure from the acoustic-oriented production of her previous album Goodbye Lullaby, featuring a more pop and upbeat sound juxtaposed with power and piano ballads. Avril Lavigne also incorporates electronic music, industrial and punk rock. The album features two vocal collaborations: Kroeger and American industrial metal singer Marilyn Manson.
