Musician and composer Annie Garlid studied English at Smith College, viola performance at New England Conservatory, early music at the Hochschule für Musik in Cologne, and ensemble singing at the Schola Cantorum in Basel. In 2018 she began her Ph.D. in music at New York University, where she researches recent experimental music.

As a viola player and singer, Annie works in early music, experimental music, and contemporary classical music. She appeared on Holly Herndon’s 2019 album PROTO and Caterina Barbieri’s 2019 album Ecstatic Computation. She has collaborated and performed with a number of other composers and artists, including Rosemarie Trockel, Bill Kouligas, Emptyset, Nile Koetting, Cat Lamb, Marc Sabat, and Laure M. Hiendl. She plays and sings with the Sebastians, Opera Lafayette, the American Classical Orchestra, the Cramer Quartet, De Nieuwe Philharmonie Utrecht, the Netherlands Bach Society, the Handel & Haydn Society, and Tafelmusik. As a violist she has worked with Pierre Boulez, Masaaki Suzuki, David Robertson, Peter Eötvös, Kristian Bezuidenhout, Bernard Labadie, and Harry Christophers. She released her debut album as UCC Harlo in 2019 and her second album, Topos, in 2023. Under that moniker she has since toured internationally, licensed her music to Chanel and JW Anderson, and produced remixes for the Amsterdam duo Know V.A. and the NYC artist NY Graffiti.
