When Leopold of Anhalt-C�then died in 1728, his former Kapellmeister had not forgotten the five brilliant years he had spent in the prince's service. He dedicated to his memory a mourning cantata almost entirely based on the music of two major works of the mid-1720s, the Trauer-Ode and the St Matthew Passion. Although the score is lost, the wordbook and other sources of information have now made it possible to reconstruct the work. Rapha�l Pichon's first recording for harmonia mundi was voted recording of the year at the 2015 Victoires de la Musique Classique awards.
