Following the sensational discovery of previously unknown Bach works at the end of last year, further historical sources relating to Johann Sebastian Bach's church music period have come to light in Leipzig. Around 60 previously unknown files with manuscripts from the composer's circle were discovered in the city archives, including documents by Bach himself as well as the writer Johann Christoph Gottsched and the composer Georg Philipp Telemann, as announced by the Saxon Academy of Sciences in Leipzig.
The files were found at the beginning of last year by the musicologist Bernd Koska as part of the "Bach Research Portal" research project. The evaluation took a long time, as the material was extensive and complex, explained Koska.
