Pianos Become The Teeth is an American post-rock inspired screamo band that formed in 2006. They perform a style of music inspired by post-rock and early screamo acts, and are a part of "The Wave"—an in-joke began by friends Touche Amore, La Dispute, Defeater, and Make Do And Mend, all playing a form of post-hardcore music. The group reissued their well received debut album Old Pride in 2010 through Topshelf Records.
