Johann Gottlieb Graun became a member of the small court orchestra of the Prussian Crown Prince Frederick in Ruppin in 1732, which Carl Heinrich also joined in 1735. With Friedrich's ascension to the throne in 1740, Johann Gottlieb was appointed concertmaster and Carl Heinrich kapellmeister of the royal court. Johann Gottlieb remained until the end of his life closely linked to Frederick the Great, as concertmaster and chamber musician. Whilst his brother Carl Heinrich became an important figure at the new Berlin Court Opera, Johann Gottlieb strongly influenced the musical life of Berlin and early classicism in general as a violinist and composer. One can no longer determine with any certainty which of the brothers wrote the oboe concertos recorded here the existing sources are too unclear and the differences in their personal styles are too slight. What is certain, however, is that the name "Graun" was a kind of seal of approval in those days for zestful music rich in ideas an estimation still valid today, as is readily apparent when listening to these concertos. The oboist Xenia Löffler has distinguished herself as a specialist for the North German repertoire of this period, as in her recordings with oboe concertos from the Dresden Court and with works from the Dresden Pisendel Collection (ACC 24202 and 24222). Alongside her teaching activities at the Academy of the Arts in Bremen, she is a member of the Akademie für Alte Musik Berlin and in great international demand as a soloist.
