Alexander/Werner Duo
Introduction
French-born soprano and composer Héloïse Werner is currently an Associate Artist at Wigmore Hall and is "quickly becoming a latter-day Cathy Berberian or Meredith Monk" (The Times), in demand as both a composer and soprano. Her anticipated second album “close-ups” was released to critical acclaim in June 2024 with Delphian Records. Colin Alexander is a cellist and composer working across a range of disciplines and traditions. Recent projects have included a new electro-acoustic commission for flamenco dancer, live cello and electronics for Resolution Festival 2025, a world premiere at London’s Wigmore Hall and a series of performances of his own solo cello suites - works described by Fiona Maddocks in The Observer as “quixotic and otherworldly, and strongly recommended”.
As a duo, they regularly collaborate with artists such as Kit Downes, Max Baillie and Jas Kayser, and have recently performed at London’s Southbank Centre, Barbican Centre and Wigmore Hall as well as End of the Road Festival and Deal Festival. They are often heard on BBC Radio 3 and have been an ensemble-in-residence for the composition students at the Royal College of Music in the 24/25 season.

Dublin International Chamber Music Festival
Royal Irish Academy of MusicJun 2026Werner and Alexander both proved themselves excellent communicators about their music... Timbral experimentation and ensemble interplay were the most memorable aspects, with both voice and cello (and, in Thunder Clears, a small handheld percussion instrument) exploring unconventional techniques throughout. Werner’s often vibratoless singing seemed tailor-made for this repertoire, and her intonation on several demanding staccato passages was impeccable. Alexander’s mastery of harmonics, left-hand pizzicato and microtones was likewise on near-constant display.
