The Sixteen are a United Kingdom-based choir and period instrument orchestra; founded by Harry Christophers, it started as an unnamed group of sixteen friends in 1977, giving their first billed concert in 1979. The group performs early English polyphony, works of the Renaissance, Baroque and early Classical music, and a diversity of 20th-century music. The Sixteen are "The Voices of Classic FM", TV media partner with Sky Arts and associate artists of the Southbank Centre in London and Bridgewater Hall in Manchester. The group promotes an annual series at the Queen Elizabeth Hall as well as the Choral Pilgrimage, a tour of Britain's finest cathedrals: bringing music back to the buildings for which it was written. The Sixteen featured in the BBC Four television series Sacred Music, presented by actor Simon Russell Beale. A second series was broadcast on BBC Four in 2010. The Sixteen tour throughout Europe, Japan, Australia and the Americas and have given regular performances at major concert halls and festivals worldwide, including the Barbican Centre in London, the Bridgewater Hall in Manchester, the Concertgebouw in Amsterdam, the Sydney Opera House, Tokyo Opera City and the Vienna Musikverein. They have also performed at the BBC Proms and the festivals of Granada, Lucerne, Istanbul, Prague and Salzburg. In addition, The Sixteen's period orchestra have taken part in semi-staged performances of Purcell's Fairy Queen in Tel Aviv and London, a fully staged production of Purcell's King Arthur in Lisbon's Belem Centre, followed by new productions of Claudio Monteverdi's Il ritorno d'Ulisse in patria at Lisbon Opera House and The Coronation of Poppea at the English National Opera. The Sixteen have an education programme and recent projects include a series of school matinées for hundreds of primary school children in Bury St Edmunds, Liverpool and Southwell under the national Sing Up initiative. The Sixteen also have close ties with the Guildhall School of Music and Drama and Trinity College of Music, offering opportunities for young people about to embark on careers as professional musicians.
