For some reason, in the last few weeks, I have not managed to listen to Slovakian radio Rádio Klasika online with a decent sound quality. If you are more lucky than I am, you could be interested in this programme devoted to Roman Berger:
Korczak in memoriam, fragments for string quartet; Sonata for violin and piano on motifs by Karol Szymanowski; exceprts from Five studies for piano.
Broadcasts: Sunday March 10 at 8am and 6pm, possibly also Monday March 11 at 4am, 2pm
Rádio Klasika can be heard online from this page:
