The French are often accused of having little interest in classical music. However...
The weekly magazine Ici... Radio-Cité, ran a contest in May 1938: Radio-Cité listeners were asked to rank the three best recent broadcasts, and the person (out of 813 responses!) who gave “the trifecta” was given a prize.
The broadcast that comes out on top is that of the concert by the Berlin Philharmonic and Furtwängler at the Paris Opéra on May 8, 1938.
For the record, the concert featured the overture to Cherubini's Anacreon, Schumann's 4th Symphony, the overture to Schubert's Rosamunde, the 2nd suite from Ravel's Daphnis et Chloé, and Strauss' Don Juan.
Radio-Cité, a station closely linked to the Publicis group, broadcast on medium wave — 280.9 m — with a 2kW transmitter located in Argenteuil. It went off the air on June 13, 1940.
