London Voices (sometimes known as London Sinfonietta Voices) is a London-based choral ensemble led by Terry Edwards, who founded the ensemble in 1973. They have been involved in numerous recordings of operas and soundtracks including The Cook The Thief His Wife & Her Lover, Ravenous, the Star Wars prequel trilogy, Lucia di Lammermoor, The Lord of the Rings series, the Harry Potter series, Heavy Metal, The Mission, Enemy at the Gates, La traviata, and The Passion of the Christ. They have recorded with such diverse artists as Luciano Pavarotti, Dave Brubeck, Amy Grant, and Queen.

As few as three or as many as 150 singers can be part of the group at one time, and more than one unit of London Voices can be deployed to perform at various venues. Their official website does not attempt to catalog all of the singers who have worked with the group.
