Greer grew up in Michigan and eventually moved to Washington, D.C., where she became heavily involved in the city's D.I.Y. music scene. For a time, she sang for and toured with Chain and the Gang, and in 2012 she co-founded the band Priests. The group became highly active over the next several years, touring often and releasing critically acclaimed albums such as 2017's Nothing Feels Natural. Greer and other members of Priests also launched the Sister Polygon record label, a completely independent imprint that released early work from bands like Gauche, Downtown Boys, Snail Mail, and many others. Concurrent with her work in Priests, Greer was exploring solo music as a side project, leaning more into electronic experimentation and production work on several EPs released as KAG.
After their 2019 album The Seduction of Kansas, Priests went on an indefinite hiatus and Greer relocated to Los Angeles. Her move coincided with the onset of the COVID-19 pandemic, and she spent her first many months in L.A. isolated and working on new solo material. Greer wrote, recorded, mixed, and produced all the material for her first proper solo album, Barbarism, over the course of the next two years, and the record was released on the FourFour label in June 2022. ~ TiVo Staff, Rovi
