Tini Mathot was born in Amsterdam. She studied piano and harpsichord at the Sweelinck Conservatory in her native town.
She works in tight collaboration with her husband (and former teacher) Ton Koopman with whom she regularly performs in concert halls all over the world. Their repertoire for either two harpsichords, harpsichord and pianoforte, harpsichord and organ or two organs, ranges from well-known to rediscovered unknown works.
Tini Mathot plays regularly as a soloist, continuoplayer or accompanist. She is a founding member of the Corelli Ensemble, together with recorder player Reine-Marie Verhagen. Her recording of Haydn trios together with Jaap ter Linden and Andrew Manze was awarded a Diapason d’Or.
In a 2005 recording she accompanied baritone Klaus Mertens in Schubert’s Winterreise, playing an original Rosenberger fortepiano. On her most recent CD she plays both organ and harpsichord, performing J.S. Bach’s triosonatas together with Reine-Marie Verhagen (recorder).
As recording producer for Ton Koopman and the Amsterdam Baroque Orchestra & Choir and other leading ensembles she has produced numerous records for Erato, Teldec, Antoine Marchand / Challenge Classiscs and other labels.
Tini Mathot is professor of harpsichord at the Royal Conservatory The Hague.
Born in Kleve, Germany, Klaus Mertens began his im- pressive career both at home and abroad immediately after graduation, having worked with renowned „early music“ specialists such as Ton Koopman, Frans Brüg- gen, Nicholas McGegan, Philippe Herreweghe, Gus- tav Leonhardt, Nikolaus Harnoncourt; as well as great conductors of classical repertoire such as Gary Bertini, Herbert Blomstedt, Sir Roger Norrington, Enoch zu Guttenberg, Jun Märkl, Kent Nagano, Hans Vonk, Kenneth Montgomery, Ivan Fischer, Andris Nelsons and many others.
Klaus Mertens has successfully worked with famous orchestras over the world, such as the great orchestras in Berlin including Berliner Philharmoniker, Gewand- haus-Orchester Leipzig, Dresdner Philharmonie, Con- certgebouw-Orchester Amsterdam, Tonhalle Orchester Zürich, Jerusalem Symphony Orchestra, Saint Louis Symphony Orchestra, Chicago Symphony Orchestra, Tokyo Metropolitan Symphony Orchestra; as well as baroque orchestras such as Amsterdam Baroque Or- chestra and various chamber music ensembles.
He is also a celebrated guest at important festivals throughout the world.
Klaus Mertens is one of the most sought-after inter- preters of baroque oratorio repertoire, and has recor- ded great vocal works of J. S. Bach with many different conductors. The recording of all Bach cantatas with the Amsterdam Baroque Orchestra initiated by Ton Ko- opman finished in October 2003. This project, which took 10 years and included concert tours throughout Europe, America and Japan, marked a highlight in his carrier; he is the first and only singer to have sung all of Bach’s vocal works for a complete CD recording series as well as in concerts.
However, Klaus Mertens is equally devoted to perfor- ming chamber music and Lieder. His repertoire expands from Monteverdi to contemporary composers, inclu- ding some that were written especially for him. He is also committed to discovering and revitalizing hitherto unheard music.
A discography of 175 CDs and DVDs along with radio and television broadcasts testifies to Klaus Mertens‘ competence as a versatile singer.
