Amsterdam Baroque Orchestra

The Amsterdam Baroque Orchestra & Choir is a Dutch early-music group based in Amsterdam.
The Amsterdam Baroque Orchestra & Choir was created in two stages by the conductor, organist and harpsichordist Ton Koopman. He founded the Amsterdam Baroque Orchestra in 1979 and the Amsterdam Baroque Choir in 1992. They have performed in concert halls such as the Concertgebouw Amsterdam, Barbican Centre London, Konzerthaus, Vienna, Lincoln Center New York and Tokyo Metropolitan Theatre.
The first concert of the choir and orchestra premiered two works of Heinrich Ignaz Biber, Requiem and Vespers, at the 1992 Festival of Early Music in Utrecht.
In 1994, Koopman embarked on a ten-year project to conduct the group in recordings and performances of the complete vocal works of Johann Sebastian Bach. His more than 200 cantatas were recorded in 22 volumes, first under the label Erato, since 2003 Challenge/Antoine Marchand Records, reissuing also the former volumes.
