Liszt concerto in
Berlin with the Philharmonic orchestra, conducted by Kreutzer. During her career, she held numerous concerts, both in Norway and abroad. After the
German occupation of Norway, Aarvold Glaser's husband Ernst, who was Jewish, started to become the target of anti-Semitic attacks which led him to flee to Sweden in November 1942. Kari and her daughters then fled Norway a few days later to join him and she managed to continue with her music career whilst in Sweden. == Death ==
