The Kardosch Singers completed tours in Denmark and the Netherlands, had radio appearances in Copenhagen, Hilversum, Frankfurt and Berlin, as well as concerts throughout Germany and a six-month engagement with the Theater am Kurfürstendamm in Berlin. Between 1932 and 1935, they recorded about 80 pieces for Telefunken, Odeon, and the Deutsche Grammophongesellschaft. The ensemble was involved in several film productions in 1932 and 1933, most of which have not survived. In the 1933 film Roman einer Nacht they visibly appear as singers in a ball scene.
