This concert was part of a mini-Strauss festival in London in June 1902.  Together with a performance four days earlier of Enoch Arden (which, like Das Schloss am Meer, had been written for Possart), it marked Strauss’s London debut as pianist.  (In December 1897 he had conducted Tod und Verklärung and Till Eulenspiegel , together with works by Mozart and Wagner at Queen’s Hall).  The Hungarian violinist Elkan Kosman was Leader of the Queen’s Hall Orchestra at the time.
