In 1834, the autograph collector Georg Poelchau discovered the musical estate of Georg Michael Telemann, the grandson of Georg Philipp Telemann, on the tower of the Riga Cathedral. This estate, in turn, consisted mostly of score autographs of the grandfather. Part of this treasure is a bundle of nine manuscripts by Telemann from the 1760s as well as the fragment of a letter with a note by the composer: "I was willing to let my pen rest for a while, because I felt a noticeable decrease in my face; however, a newspaper journal fell into my hands, where I read: the Serene Landgrave of Darmstadt would be celebrating your name festival on August 25. I immediately got into an enthusiasm, and made the draft for pieces coming here...". This collection of overtures, symphonies and divertimenti, Telemann's swan song from the 86th year of his life, "is certainly one of the most peculiar and enigmatic, rare and wonderful pieces that has sprung from this musical genealogy - it is a true musical chamber of wonders" (Wolfgang Hirschmann). With the first complete recording of this Darmstadt volume, a long-cherished wish of Michael Schneider, La Stagione and myself comes true!
