I saw a notice that the very first performance of a recently-discovered flute concerto by W. A. Mozart will be live-streamed from Istanbul on December 2 by way of Tutti Mozart's FaceBook page, but it is not clear (to me, at least) if this is a work that is totally original or a piece written by Johann Baptist Wendling with some help from Mozart. Somehow I imagine that a discovery of a new Mozart concerto would have made large ripples in the musicological ether. I can't seem to find any at this point.
People interested will have to do some calculations regarding the time of the concert, taking the International Date Line into consideration. I might sit this one out, but I'm sharing the link here anyway.
