Oliver Leith (b.1990) is a London-based composer. He writes music that is “deadpan, subversive, quietly anarchic, disarmingly heart-sore and sweet-sour” (BBC Radio 3, Kate Molleson), which has been performed by the BBC Symphony Orchestra and Ilan Volkov, the LA Philharmonic, Royal Northern Sinfonia, London Sinfonietta, members of the Philharmonia Orchestra, EXAUDI, and Trio Catch.

His works have appeared at the BBC Proms, Tanglewood Music Centre, Wigmore Hall, Aix Festival, Transit Festival, the Darmstädter Ferienkurse, Heidelberg Festival, Riga’s White Night Festival and Liszt Academy (Budapest). Accolades include an Ivor Novello award for Honey Siren (2019), a 2016 British Composer Award for A Day at The Spa, premiered by Kaleidoscope Saxophone Quartet, and the 2014 RPS Composer Prize.

He was previously Guildhall School of Music & Drama’s Doctoral Composer-in-Residence at the Royal Opera House. This led to the creation of Leith’s acclaimed debut chamber opera Last Days, which premiered at the Royal Opera House’s Linbury Theatre in 2022 with a sold-out run of performances; it received its US premiere from the LA Philharmonic and Thomas Adès in February 2024 at Walt Disney Hall.

The 90-minute piece, with a text by Matt Copson and the composer, is based on Gus Van Sant’s 2005 film. Last Days traces the self-destructive spiral of a rock star escaped from rehab; its debut production, co-directed by Anna Morrissey and Matt Copson, starred Agathe Rousselle in the non-singing lead role of Blake, with costumes by Balenciaga. The opera features a recording of an Italian verismo­-style aria written for Caroline Polachek and produced by Danny L Harle.
