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.

Bass-baritone Klaus Mertens is celebrated by critics as an “excellent master of his craft” for his “unique power of expression, his congenial timbre, his keen intuition for text, as well as his convincing manner of making music”. He has recorded more than 200 CDs, including the entire works of Johann Sebastian Bach and Dietrich Buxtehude. These testify eloquently to his art of singing, which spans a great arch from Monteverdi to his contemporaries. Characterized as “the most significant Telemann interpreter of our time”, Mertens received the Telemann prize of the city of Magdeburg in 2016. In 2019, he was honored with the renowned Bach medal of the city of Leipzig as the “ideal interpreter of Bach’s cantatas and passion texts”.

His lyric tenor voice had a youthful glow, yet he sang with plaintive beauty and piercing insight.

Precise vocal control, clear diction, intelligent musicality, and an ability to get to the heart of everything he sings all ensure Christoph Prégardien’s place among the world’s foremost lyric tenors. Especially revered as a Lieder singer, he also regularly appears with renowned orchestras the world over. He has worked with the Berlin and Vienna Philharmonics, Amsterdam Concertgebouw Orchestra, Philharmonia Orchestra, Orchestre Philharmonique de Radio France, as well as the Boston and San Francisco Symphonies, alongside conductors such as Barenboim, Metzmacher, and Thielemann. His wide orchestral repertoire includes the great baroque, classical, and Romantic oratorios and passions, as well as works from the 17th and 20th centuries. In opera, his roles have included, among others, Tamino, Almaviva (Il barbiere di Siviglia), Fenton (Falstaff), Don Ottavio, Titus, Ulisse, and Idomeneo.

The current season begins with recitals at the Oxford International Song Festival, together with Yaara Taal in Munich, at Haus Marteau, in Monheim, and in Weiden as well as with Michael Gees in Marbach and Blaibach. In December, he returns to the Filharmonie Brno, where he most recently performed Handel’s Messiah, to sing songs from Mahler’s Des Knaben Wunderhorn under Dennis Russell Davies. This is followed in January by two trio concerts in Switzerland with violinist Leila Schayegh, featuring works by Beethoven and Schubert; the programme will also be presented at the Schubertiade Schwarzenberg in June. Further engagements include a recital at the Festival internacional de música de Bogotá and the closing concert and a masterclass at the Leeds Song Festival. He will also serve as a jury member at the Concours Reine Elisabeth and the Bachwettbewerb Leipzig. A major project of recent seasons has been Johannes Maria Staud’s Die schöne Müllerin/These Fevered Days, combining Schubert’s cycle in a newly orchestrated version with seven new songs after texts by Emily Dickinson. Following the 2024 world premiere with Ensemble Kontraste, highly successful performances followed last season with Klangforum Wien (Klangspuren Schwaz and Vienna Konzerthaus) as well as with the Remix Ensemble in Porto.

His extensive experience singing the Evangelist roles, together with his close working relationship with conductors such as Nagano, Chailly, Herreweghe, Harnoncourt, Luisi, and Gardiner, have provided the perfect base for his increasing dedication to conducting this repertoire as well. Following the success of his conducting debut in 2012 leading Le Concert Lorrain and the Nederlands Kammerkoor, he now regularly conducts renowned ensembles like the Balthasar Neumann Choir, Dresdner Kammerchor, Collegium Vocale Gent, and RIAS Kammerchor. In 2024, he took to the podium for Bach’s St Matthew Passion with Vespres d’Arnadí and the Cor de Cambra del Palau in Barcelona, returning to the latter in 2025 for a tour of Bach’s Christmas Oratorio with the Belgian ensemble Il Gardellino.

The singer has recorded much of his repertoire on a discography of over 150 albums, which have received awards such as the Orphée d’Or of the Académie du Disque Lyrique, the Edison Award, the Cannes Classical Award, and the Diapason d’Or. For the label Challenge Classics, he has recorded Schubert’s Schwanengesang with Andreas Staier and Die schöne Müllerin with Michael Gees, which was selected as Editor’s Choice by Gramophone magazine and awarded the MIDEM Record of the Year award. Shortly thereafter followed recordings of Hugo Wolf’s Italienisches Liederbuch with Julia Kleiter, Between Life and Death, Wanderer, and the Grammy-nominated Winterreise disc – all with Michael Gees – as well as Father and Son with his son Julian Prégardien. His Schubert CD Poetisches Tagebuch with Julius Drake was awarded the German Critics’ Award 2016. His most recent releases include one recorded in collaboration with the Warsaw Chopin Institute with pianist Christoph Schnackertz featuring songs by Paderewski, Moniuszko and Duparc, and a new recording of Schubert’s Schwanengesang and Schumann’s Liederkreis, Op. 39 (with Julius Drake). In 2023, the Etcetera label released an album of Bach cantatas recorded with Stephan Schultz and Le Concert Lorrain, featuring Christoph Prégardien as baritone.

Teaching remains an important part of Christoph Prégardien’s musical life. Following many years at the Hochschule für Musik und Theater in Zurich and a professorship at the Academy of Music in Cologne, he continues to give masterclasses for young singers around the world.

The Scottish tenor, Paul Agnew, read music as a Choral Scholar at Magdalen College, Oxford. After earning his degree, he became associated with the Consort of Musicke, and remained a member of this wonderful early music ensemble for many productive years. At these early stages of his career, he has also made numerous appearances with The Tallis Scholars (Director: Peter Phillips), The Sixteen (Director: Harry Christophers) and the Gothic Voices, before finally striking out on his own as a soloist in the early 1990's.
