For Wilbert Hazelzet’s second disc for Glossa, the stylish Dutch flute player covers a selection of pieces of music by composers who, with varying levels of certainty, can be regarded as having been pupils of Johann Sebastian Bach: Abel, Kirnberger, Krebs, Müthel and Goldberg – whose C major Sonata was for a long time regarded as being by Bach himself (as his BWV 1037). Cellist Jaap ter Linden and harpsichordist Jacques Ogg accompanied Hazelzet on this beautiful recording.

Le prestigieux Collegium Musicum créé par Telemann fut l'orchestre attitré de Bach lorsqu'il prit ses fonctions à Leipzig. Il put ainsi tester avec cette formation de nouvelles associations de timbres que l'on retrouve dans le Concerto pour clavecin BWV 1052, le Concerto pour piano forte en si bémol majeur et le Triple Concerto BWV 1044. Il s'agit parfois de transcriptions et d'adaptations, d'œuvres originellement pour violon, mais le résultat est étonnant de brio et de force expressive. Il faut écouter ce fameux Triple Concerto pour flûte, violon, clavecin et cordes porté par les couleurs de l'Akademie für Alte Musik : on y retrouve l'impulsion rythmique, la richesse de tempérament du Concerto Brandebourgeois n° 5, un esprit de danse et de fête qui privilégient sans conteste le clavier.

Johann Forkel, the biographer of J.S. Bach, numbered Müthel among the most remarkable of Bach’s pupils. Another of the great chroniclers of 18th century music, Charles Burney, described Müthel's works as 'so full of novelty, taste, grace, and contrivance, that I should not hesitate to rank them among the greatest productions of the present age.’ In Müthel's five concertos for keyboard and strings we nevertheless meet a distinctly individual composer, displaying sophisticated rhythms and harmonic playfulness. Presenting them on this set of two CDs, the young Polish harpsichordist Marcin Świątkiewicz makes his début on BIS. He is supported by his compatriots in the acclaimed period band Arte dei Suonatori, who clearly relish the often intricate and always eventful orchestral parts.

Johann Gottfried Müthel was the last pupil of the great Johann Sebastian Bach. He was present at the master’s deathbed, and he performed the funeral services, taking over the duties of the deceased Cantor. Mühtel’s music (“full of novelty, taste and grace” according to the great art historian and traveller Charles Burney) is of a wide variety: his Organ Fantasias are imposing, monumental and substantial, his chorale preludes offer intimate meditations on the chorale texts, all of it written in a highly original, dynamic musical language full of contrasts and instrumental virtuosity.
