The joy of experimentation was a central feature of Bach's compositional thinking: the drive to continually push the boundaries of musical forms and the possibilities of instruments and voice—in service of a perfection that is both aesthetic and spiritual.

The selection of works on harpsichordist Cristiano Gaudio's second solo album, whose debut recording was awarded a Diapason d'Or and the Choc de l'Année by Classica magazine, is fueled by this spirit. From the dizzying virtuosity of the Chromatic Fantasia and Fugue to the contrapuntal density of the Ricercare à 6 from the Musical Offering, from the art of transcription to the "twelve-tone" closing fugue of the first part of the Well-Tempered Clavier, Bach's music unfolds here as an intellectual adventure—and as a tangible boundary experience.
