In this second volume (double-cd) of the Opera Omnia of Dieterich Buxtehude, Ton Koopman gives us his new reconstruction of Buxtehudes only surviving Abendmusik, this oratorio, also called "Das Jungste Gericht", that survived without attribution as an incomplete set of parts in the Uppsala University Library. As the style is similar to Buxtehudes lost Abendmusiker, this oratorio is almost certainly from his hand.

Dieterich Buxtehude (Dietrich, Diderich) was a German-Danish organist and a highly regarded composer of the baroque period. His organ works comprise a central part of the standard organ repertoire and are frequently performed at recitals and church services. He wrote in a wide variety of vocal and instrumental idioms, and his style strongly influenced many composers, including Johann Sebastian Bach. Organist at the Marienkirche in Lübeck for most of his life, Buxtehude is considered today to be the leading German composer in the time between Schütz and Bach.

Ton Koopman (1944) studied organ (Simon C. Jansen), harpsichord (Gustav Leonhardt) and musicology in Amsterdam and was awarded the Prix d'Excellence for both instruments. As an organist he has performed on the most prestigious historical instruments of Europe, and as a harpsichord player and conductor of his Amsterdam Baroque Orchestra (founded 1979) & Choir (1993) he has been a regular guest at venues which include the Concertgebouw in Amsterdam, the Theatre des Champs-Elysées in Paris, the Philharmonie in Munich, the Alte Oper in Frankfurt, the Lincoln Center in New York, and leading concert halls in Vienna, London, Berlin, Brussels, Sydney, Melbourne, Madrid, Rome, Salzburg, Tokyo and Osaka.

Ton Koopman edited the complete Handel Organ Concertos for Breitkopf & Härtel and will edit a number of Buxtehude works for Carus Verlag. He is president of the International Dieterich Buxtehude Society.

He recorded a.o. for Erato, Teldec, Sony, Philips and DGG. In 2003 he created Antoine Marchand, his own sub-label of Challenge Records. Here he publishes the Complete Bach Cantatas, as well as his other recent and future recordings, including this Complete Buxtehude project.
