Ton Koopman is a leading figure in Early Music and historically informed performance practice. As organist and harpsichordist Ton Koopman has performed all over the world and played the most beautiful historical instruments of Europe. His Amsterdam Baroque Orchestra & Choir has gained worldwide fame as one of the best ensembles on period instruments. Between 1994 and 2004 Ton Koopman and ABO&C have recorded all sacred and secular cantatas by Johann Sebastian Bach, an extraordinary project that earned international acclaim. After that Koopman recorded the complete works by Bach’s predecessor, Dieterich Buxtehude. Besides performing as a soloist and with his ABO&C, Ton Koopman is very active as a guest conductor for modern orchestras and also devotes part of his time to teaching. Ton Koopman is president of the International Dieterich Buxtehude Society and, since 2019, president of the Leipzig Bach Archiv.

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. Ton Koopman and the ABO & ABC are regular guests at the major concert halls of Europe, the USA and Japan. In the 2008/09 season they will tour extensively in Europe (Amsterdam, Paris, Madrid, Vienna, Milan, Cologne, Dresden, Düsseldorf etc) and in Far East with concerts in Hong Kong, Seoul and Tokyo.

Tini Mathot was born in Amsterdam. She studied piano and harpsichord at the Amsterdam Sweelinck Conservatory.
She enjoys a close collaboration with her husband and former teacher Ton Koopman. Together they perform many popular and lesser known works, giving recitals and performing in chamber music projects in the major concert halls of Europe, the United States and Japan. Tini Mathot regularly appears as a soloist together with Ton Koopman in concertos for two (or more) harpsichords and orchestra. She has recorded double concertos of J.S. Bach, C.P.E. Bach, J.F. Reichardt and C. Schaffrath with the Amsterdam Baroque Orchestra.
Tini Mathot is a member of the Corelli Ensemble, whose members include Reine-Marie Verhagen. The ensemble was awarded the Diapason d’Or in France for its recording of Haydn trios (with Andrew Manze and Jaap ter Linden), issued by Erato. The CD recording of Schubert’s ‘Winterreise’, sung by the baritone Klaus Mertens with Tini Mathot playing an original Rosenberger fortepiano, was released in 2005, followed by a recording of J.S. Bach’s organ trio sonatas with Reine-Marie Verhagen (recorder) and Tini Mathot (organ and harpsichord) in 2008, both CDs issued by Challenge Classics.
In her capacity as producer for Ton Koopman’s Amsterdam Baroque Orchestra & Choir and also for other ensembles, Tini Mathot has produced numerous CDs for Erato, Teldec and Antoine Marchand/Challenge Classics, among other labels. She is the producer of the complete series of Bach cantatas by Ton Koopman and the ABO&C as well as the Opera Omnia of Dieterich Buxtehude, which Ton Koopman is currently working on. In addition to these activities Tini Mathot teaches harpsichord at the Royal Conservatory of The Hague.
 Tini Mathot plays on a fortepiano by Mathias Müller, Vienna c. 1810 (with a range of 6 octaves FF-f4, an Empire-style case with bronze fittings and Caryatid legs), from the collection of Edwin Beunk, Enschede (NL). The instrument is typical of the Viennese building style around 1810. Mathias Müller had a reputation as an innovator with regard to instruments and was ‘Kaiserlich-Königlich priviligiert’.
