The reason for the recent short hiatus on this blog is the following detailed review article (in German, the language of Mozart):
Das Forschungsprojekt "W. A. Mozart und sein Wiener Umfeld": Mozartforschung in Wien am Beginn des 21. Jahrhunderts
This review deals with a supposedly scholarly research project concerning archival probate records of members of "Mozart's Viennese Circle". The project, which was initiated by the "Mozartgemeinde Wien" (The Vienna Mozart Society), was actually funded with 4,000(!) Euros by the City of Vienna's Department of Culture. Because the result of this enterprise is so shockingly worthless, it provides a classic example of what is gravely amiss in current Viennese Mozart research.
The reaction of The Vienna Mozart Society to my review is dealt with in the post The Vienna Mozart Society Responds.
