Soprano Juliet Fraser has a repertoire dominated by the very old and the very new. Specialising in the gnarly edges of contemporary classical music, Juliet is an active commissioner of new repertoire and has worked particularly closely with composers Laurence Crane, Pascale Criton, Michael Finnissy, Bernhard Lang, Cassandra Miller and Rebecca Saunders. Recent festival highlights include Aldeburgh Festival, Huddersfield Contemporary Music Festival, Acht Brücken (Köln), MaerzMusik (Berlin), Milano Musica, Rainy Days (Luxembourg) and TIME:SPANS (NYC).

She regularly performs as a guest soloist with ensembles such as MusikFabrik, Klangforum Wien, Ensemble Modern, Plus-Minus and Talea, with Quatuor Bozzini, and as a duo with pianist Mark Knoop. Much of her commissioning focuses on creating a body of new work for voice and tape/electronics or for voice and piano. She has recently commissioned pieces from Lara Agar, Laurence Crane, Nwando Ebizie and Newton Armstrong. Juliet is also known for breathing new life into existing repertoire such as Schoenberg's Second String Quartet, Babbitt’s Philomel, Vivier’s Bouchara, Feldman’s Three Voices and Grisey’s Quatre chants pour franchir le seuil. 

In 2015 she released her debut disc, Feldman's Three Voices (on Hat Hut). Recent releases include all four of her 'Carson Commissions': Laurence Crane's Natural World (Another Timbre), Lara Agar's This Unquiet Autumn (YouTube), Nwando Ebizie's I Birth the Moon (YouTube) and Newton Armstrong's The Book of the Sediments (all that dust). Her discography also includes acclaimed recordings of Renaissance polyphony by Lassus, Vitoria and Byrd with Collegium Vocale Gent (directed by Philippe Herreweghe), Bach cantatas with Gli Angeli Genève and, most recently, the late madrigals of Carlo Gesualdo with EXAUDI Vocale Ensemble, which she co-founded in 2002 with composer/conductor James Weeks. Her latest album (NEOS) presents music by Chaya Czernowin, Beat Furrer, Enno Poppe and Rebecca Saunders. 

Juliet recently launched VOICEBOX, an initiative supporting singers specialising in contemporary vocal performance which is delivered in partnership with Britten Pears Arts, City, University of London, sound festival (Aberdeen) and Dartington Music. She has delivered masterclasses or short courses for Darmstadt Summer School, Voix Nouvelles Academy at Royaumont, Britten Pears Young Artist Programme, Dartington Music Summer School, Southampton University and Leeds College of Music. She has served on juries for The Arts Foundation, NCH/Sounding the Feminists, the Ivors Composer Awards and Royal Philharmonic Society, and been a panellist for ROH's Engender Network and Cheltenham Music Festival's Composium. Alongside her work on stage, Juliet enjoys writing words about being a performing artist. Recent essays have been commissioned by Britten Pears Arts, MaerzMusik Festival and the Fragility of Sounds lecture series, presented at Darmstadt and at the Fourth International Conference on Women's Work in Music, and published in Glissando (#43, co-authored with Fay Jennett), TEMPO and by Wolke. She is currently serving as a trustee on the board of Morabe Rural Music. In 2023 Juliet was awarded an honorary doctorate by the University of Southampton. 

Juliet is the founder and artistic director of eavesdropping, a festival of new music held at Cafe OTO in East London, co-director with Mark Knoop and Newton Armstrong of all that dust, a little independent label for new music, and programme director of VOICEBOX.
