This is the first recording dedicated to J.B. Janson, virtuoso, composer and teacher of the second half of the 18th Century. Together with the Duport brothers, he was the major representative of the French cellist school, and in the year of the foundation of the Paris Conservatory he became it's first professor. Unjustly forgotten by history, his first compositions represent in an exemplary way the turning point of European musical taste from the Style Galant to Classicism. In these first two works, the wealth of technical innovations, as well as the narrative and visionary energy of musical inventions, lead us to think that the perfect alchemy arisen from the encounter of a brilliant and infinitely curious mind, which certainly was Berteau's, with the miracle of a child prodigy, ended up in an unfulfilled promise, a broken dream that dissolved into oblivion. Thus the famous Jansons will be forgotten, while the fame of the Duports lingers in the historical memory up to our days.
