Thanks very much indeed for posting this link. My own personal interest lies more in what was played (and how it was received/reviewed) rather than who the players were, important though that is. This was, after all, the era of Brahms whose chamber music overshadowed that of everyone else; what interests me is the large group of Brahms' contemporaries, some of whom we know next to nothing about, e.g. Fritz Kauffmann...
Maybe the subject of the repertoire played in that era will emerge as the project develops.
Thanks again.
Skimming digitized issues of NZM and similar journals (even with relatively little German) from the period can be helpful in that connection :)
