An Academy Award-nominated singer/songwriter and composer best known as the acrobatic, multi-instrumental member of the spirited, Grammy Award-winning indie rock collective Arcade Fire, Will Butler joined the band, which was the brainchild of his older brother Win and Win's wife Régine Chassagne, in 2003. He made his first recorded appearance on the group's acclaimed 2004 Merge Records debut Funeral, and contributed heavily to all of the band's subsequent releases. In 2013, Butler joined up with fellow musical polymath Owen Pallett to compose the soundtrack to the Spike Jonze-directed futuristic romantic comedy Her, for which he received an Oscar nomination, and in 2015 he issued his eclectic debut solo album, the Merge-issued Policy. After leaving Arcade Fire in 2021, Butler regrouped with a new band and issued self-titled 2023 album Will Butler + Sister Squares.
