Mosaic Voices was founded in 2012 by its Musical Director, Michael Etherton, as a professional a cappella choir specialising in performing, preserving and commissioning sacred music from the Jewish tradition. It is the resident choir of the New West End Synagogue, Bayswater, London. BBC Radio 3 broadcast Mosaic Voices' recording of Kol Nidrei on its In Tune programme on October 8th 2019. The recording was a new choral arrangement of Kol Nidrei written by Mosaic Voices' Resident Composer, Benjamin Till. The choir's first album, 'The Blue Book', was released in December 2018, and is now available across major platforms including iTunes and Spotify, as well as on CD.
