Since its formation in 1979 the London Sinfonietta Voices has become one of the most highly regarded groups for the performance of new vocal music in the world. Its personnel are all virtuoso singers and its numbers vary according to the demands of the works being performed. Its main aim is to highlight the finest achievements in consort composition from earlier centuries, to perform the major 20th-century repertoire and to offer composers the chance to write for virtuoso singers, thus continuing the development of consort and choral music.
