12 ensemble

Eloisa-Fleur founded the 12 ensemble, London's un-conducted string orchestra, with cellist Max Ruisi in 2012. Since forming, the group has rapidly developed a reputation as one of the UK's leading string orchestras.


A modern, versatile and virtuosic ensemble, the group is built around a core of twelve of London’s finest chamber musicians. Always playing without a conductor, the ensemble’s acclaimed performances combine the energy, excitement and creativity of a small ensemble with the breathtaking sound afforded by a string orchestra.


The 12 ensemble are in demand internationally, recently performing at leading venues including the Barbican, Royal Albert Hall, Berlin Philharmonie and Elbphilharmonie, Hamburg. The group have also made appearances at leading festivals worldwide, including a debut at the BBC Proms 2019, a residency at the Barbican’s Sound & Visions festival and performances in South Korea and Iceland, plus multiple broadcasts on BBC Radio 3. Their 2018 debut album Resurrection (including works by Lutoslawski and premiere recordings of works by Bryce Dessner & Kate Whitley), received wide critical acclaim from publications including Gramophone, The Strad & The Sunday Times.


Following the success of their debut album, the 12 ensemble released their second album Death & the Maiden in January 2020. With their own arrangement of Schubert’s iconic string quartet at its heart, the record is a highly-charged personal journey through an evolving musical landscape, featuring accompanying works by Tavener and Icelandic band Sigur Rós plus a new commission from the ROH Composer in Residence Oliver Leith.
