Numerous interesting publications were issued on the occasion of the 200th anniversary of the death of Carl Philipp Emanuel Bach. The biggest surprise, however, came 13 years later in 2001, when the archive of the Berlin Sing-Akademie was rediscovered in Kiev and sent back to the Berlin State Library. A large number of works of CPE Bach were found there; it was finally possible to make an inventory list of all the musical treasures contained in this collection. The Concerto in D minor for transverse flute and orchestra, the existence of which was known but of which no manuscript was available, is one of the many works that enriched the concert repertoire from that time onwards. And now, over a decade later, Bach’s 300th birthday offers one more occasion to highlight his genius with new insights.
