29 October 1923 was a date steeped in history. In the middle of a year of political and economic crises, the age of public radio in Germany was ushered in with the first broadcast of the "Berliner Funkstunde" (Berlin Radio Hour) from the attic of an office building on Potsdamer Platz. Radio offered entirely new possibilities for the production and reception of music. The two compositions on this CD not only benefited from these developments but also played an active role in shaping them.
