Ton Koopman founded the Amsterdam Baroque Orchestra in 1979. The group consists of internationally renowned baroque specialists who meet up several times a year and work together to prepare and perform new exciting programmes. For the musicians each concert is a new experience and Koopman's boundless energy and enthusiasm are a sure guarantee of the highest quality.
The Amsterdam Baroque Choir was founded in 1992 and it made its debut during the Holland Festival of Early Music in Utrecht performing the world première of the Requiem (for 15 voices) and Vespers (for 32 voices) by H.I.F. Biber. The recording of both of these works won the Cannes Classical Award for the best performance of 17th/18th century choral music. For its rare combination of textural clarity and interpretative flexibility, the Amsterdam Baroque Choir is considered among today’s most outstanding choirs. In 1994 Ton Koopman and the Amsterdam Baroque Orchestra & Choir embarked upon the most ambitious recording project of the last decades: the integral recording of Bach’s secular and sacred cantatas. For this extraordinary project Koopman and his ensemble received the Deutsche Schallplatten-Preis Echo Klassik. Next to the CD recordings three books have been edited and published by Ton Koopman and the musicologist Christoph Wolff and a series of six documentaries was produced and broadcasted by various TV stations.
Alongside Bach’s music the Amsterdam Baroque Orchestra & Choir has recorded all major baroque and classical works. Major recognitions include the Gramophone Award, Diapason d'Or, 10-Repertoire, Stern des Monats-Fono Forum, the Prix Hector Berlioz and two Edison Awards. In 2008 the ensemble and Ton Koopman have been honoured with the prestigious BBC Award. Since March 2003 “Antoine Marchand”, a new sub-label of Challenge Classics, took over the release of Koopman’s new recordings and among many others has published 22 CD boxes of the Bach Cantatas, a new recording of the St. Matthew Passion (on CD and DVD) and St. Markus Passion of J.S. Bach (DVD), live recorded in Milan, as well as the first seven volumes of the Buxtehude Opera-Omnia Edition.
