Showing Teeth is the stage name of Addison, a vocalist and songwriter from the United States, based in Nashville, Tennessee. The project sits in deathcore, metal, metalcore and screamo.

She first becomes known for recording vocal covers of modern metal bands from her car, including Whitechapel, Boundaries and Underoath. These performances draw praise from a number of other metal vocalists and help establish her profile online.

Showing Teeth later moves into original music with the single Labyrinth, which features Periphery drummer Matt Halpern and producer Zakk Cervini. After a live debut later the same month, she releases more singles and signs to Republic and Spinefarm Records. Her debut EP, A Fate Worse Than Loneliness, follows as the project’s first extended release.
