Jos van Immerseel is an outstanding period keyboard player who has been heard on the clavicembalo and fortepiano. Eugene Tracy, Flor Peeters, and Kenneth Gilbert were his instructors at the Royal Conservatory in Antwerp, where he won first prizes in piano, organ, and harpsichord between 1961 and 1971. During that period, he also won a number of competitions, culminating with the winning of the inaugural Paris Forum International de Clavecin in 1973. He is in demand as a soloist around the world, traveling with his own fortepiano at times, known for his musical receptiveness and responsiveness and his improvisational skills. He founded the Collegium Musicum in Antwerp, conducting that ensemble and the Collegium Vocale to expand his interest in Renaissance and Baroque music. In 1985, he found the orchestra Anima Eterna, also a period instrument group, which he has conducted from the keyboard. Much of his performing is focused on music of the Classical and early Romantic eras, although he has also recorded songs of Fauré with Max van Egmond, and of Debussy with Sandrine Piau, and the music of César Franck. Vera Beths and Anner Bylsma regularly perform and record with him, as well, most notably in Schubert's chamber works.

In addition to his performing and recording, van Immerseel keeps busy with writing articles and reviews, producing radio programs, and teaching. He has taught at the Antwerp Conservatory and Amsterdam's Sweelinck Conservatory; used the instruments in Antwerp's Vleeshuis Museum to give classes for its academy; and since 1992 has been on the faculty of the Paris Conservatoire.

Van Immerseel records for Channel Classics and Sony, among other labels. His Beethoven piano concerto recordings with Tafelmusik were noted for the cadenzas, which he wrote in keeping with the capabilities of the period instrument. However, one of his finest achievements is his recording of the fortepiano version of Haydn's The Seven Last Words of Christ.

Midori Seiler has established a multifaceted career on the concert stage, appearing as soloist, chamber player, and concertmistress with several major orchestras. She is one of the busier violinists in Europe, not simply because her highly successful concert activity has also led her into the recording studio, but owing to her teaching duties at the Liszt School of Music in Weimar and her schedule of master classes at various European locations. Not to be confused with Japanese-American violinist Midori Goto, who generally uses just her first name, Seiler typically performs on period instruments and has achieved acclaim for her incisive interpretations of Baroque repertory, particularly works by J.S. Bach and Vivaldi. But she has also received high praise for her Mozart, Beethoven, Schubert, and for her solo work in the Rimsky-Korsakov Scheherazade. Seiler has often appeared in concert with pianist Jos van Immerseel and has concertized throughout Europe, the Americas, and Asia. She has also made numerous recordings, mostly for Harmonia Mundi and Zig Zag.

Midori Seiler was born to a Japanese mother and Bavarian father in Osaka, Japan in 1969. Her parents, talented pianists both, raised her in Salzburg. Seiler's first advanced studies were in Salzburg with Helmut Zehetmair and Sandor Vegh. She had later studies with Adelina Oprean at the Basel Conservatory of Music, and with Thomas Hengelbrock at the Schola Cantorum, also in Basel.

While studying in Basel Seiler was concertmistress in the Swiss Youth Symphony Orchestra. She had further studies with David Takeno (London) and Eberhard Feltz (Berlin). From 1991, Seiler has served as a member of the Akademie für Alte Musik Berlin, becoming the ensemble's concertmistress in 2000, a post she still holds. She serves in the same capacity with Anima Eterna, the period-instrument ensemble led by pianist/conductor Jos van Immerseel.

Seiler and van Immerseel collaborated on a disc of Mozart, Les grandes sonates viennoises, on Zig Zag, which received the prestigious Diapason d'Or Award in 2002. In 2005 Seiler appeared in Carnegie Hall in an acclaimed performance of the J.S. Bach Concerto for two violins, with violinist Georg Kallweit, and the Akademie für Alte Musik Berlin, part of the ensemble's first tour of the U.S.

From 2010, Seiler has served as professor of Baroque violin and viola at the Liszt School of Music in Weimar. Among her most important recordings is the highly acclaimed 2011 Berlin Classics CD of the Bach Partitas for violin solo, No. 1, No. 2, and No. 3.
