Courtney LaPlante (born February 26, 1989) is an American singer best known as the lead vocalist of the Canadian heavy metal band Spiritbox.

[6] At the age of 15, following her parents' divorce, LaPlante relocated with her mother to Victoria, British Columbia, nearly 2,800 miles northwest of her Jacksonville, Alabama home.

[9] The group started by playing music inspired by Rage Against the Machine which resulted in a sound similar to their spinoff Audioslave,[10] but gradually gravitated toward progressive metalcore,[4] influenced by the likes of Protest the Hero and Between the Buried and Me.

[10] It was during a show that Unicron shared with fellow Victoria-based metal band Fall in Archaea that LaPlante met their guitarist, Mike Stringer.

[8] LaPlante and Stringer were no longer comfortable being the "replacement people" for the original members before them, and also desired to pursue a new creative direction.

LaPlante and Stringer got married in 2016, and two weeks after the wedding, they began investing their money into recording songs for a new project.

[11] In the interim, the two returned to find regular employment; at first, LaPlante served as a waitress, while Stringer delivered pizzas.

[26][11] She has cited Tesseract,[11] Deftones,[27] Kate Bush,[27] Tool,[26] and Amy Lee as influences;[28] though Meshuggah is her leading example in heavy metal as a whole.

At the age of eighteen, LaPlante laid down her screamed vocals for the first time on a breakdown of a song written by her brother.

[31] She said that it is necessary to push the boundaries of the metalcore genre by bringing modernity and diversity of vocal styles to stay relevant.

[21] Her vocal phrasing based on her musical expression, primarily rooted in contemporary R&B, would become a distinctive feature; she credits Doja Cat, H.E.R., SZA, and the Weeknd as influences to her clean singing.
