The Monteverdi Choir was founded in 1964 by Sir John Eliot Gardiner for a performance of the Vespro della Beata Vergine in King's College Chapel, Cambridge. A specialist Baroque ensemble, the Choir has become famous for its stylistic conviction and extensive repertoire, encompassing music from the Renaissance period to Classical music of the 20th century. They often appear with John Eliot Gardiner's orchestras, the English Baroque Soloists and Orchestre Révolutionnaire et Romantique. wikipedia
