Mozart always had a special affinity with wind instruments: for him they were essential components of his musical expression, claims French clarinettist Nicolas Baldeyrou, a globally renowned soloist who has performed with some of the greatest conductors and virtuosi: this album is the first volume of a complete set of Mozart's chamber and concertante music involving the clarinet, which he has chosen to record on period instruments, "an authentic and revelatory experience, despite the technical challenges it presents". He has enlisted the help of his musical friends, all of whom are recognised as adept practitioners of modern instruments, but sustain a strong passion for period instruments... The programme of this first release includes the Serenades KV 375 and 388 as well as Mozart's Gran Partita KV 361, a work on an exceptionally grand scale, with it's line-up of thirteen players, it's expansive duration, and it's supreme musical quality, "rising to the level of Mozart's greatest symphonies and operas".

After exploring the Gran Partita, Nicolas Baldeyrou opens the doors to concertante music in this second volume. The programme displays the two faces of Mozart: the youthful, all-conquering genius of his Parisian period, and the supreme master of his final year in Vienna - the two phases united by his overriding desire to make the instrument 'sing'. 'Performing these major works on historical instruments is not a nostalgic exercise, but an attempt to recover the music's acoustic authenticity,' says Baldeyrou. For the Concerto, the use of a copy of the period basset clarinet is essential in order to recreate the melodic line, tessitura and colours demanded by Mozart. Where the modern clarinet 'homogenises' the sound, the historical basset clarinet offers an infinite palette. With the Kolner Akademie and leading soloists, Baldeyrou plays with the intrinsic vulnerability of the instrument and sculpts each note, bringing us as close as possible to the composer's last creative impulse.

The clarinet sonatas mark the end of Brahms’s output of chamber music and perhaps its peak. Their gentleness and tenderness combine gracefully with the twilight glow that emanates from these pieces, showing a disarming simplicity close to Mozart. The Horn Trio, on the other hand, expresses the ardor and energy of a composer in his early thirties and at the height of his artistic powers. Geoffroy Couteau moves with sovereign ease from one mood to another in these works, bringing out their vividly contrasting colors and emotions in perfect unison with his attentive partners.
