The list of Furtwängler’s concerts (v. bottom of the homepage) reveals the recurring, albeit infrequent, participation of Furtwängler as a soloist in his concerts: at the piano for concertante works, but also as a partner in chamber music or an accompanist for singers. In time, such performances became even more infrequent, until he appeared at the keyboard only in the 5th Brandenburg or — albeit for an entire recital and in Salzburg — to accompany Elisabeth Schwarzkopf.
It is in a concerto of Mozart that we find him in a concert of the Berliner in Hamburg, on 17 April 1936, and here is a facsimile of the programme.
