In 1979, the Metropolitan Opera revived Kurt Weill's opera Rise and Fall of the City of Mahagonny, which had first appeared in Berlin in1929. Lotte Lenya, Weill's wife, sang the lead role of Jenny in the original Berlin production, and Teresa Stratas was Jenny in 1979 at the Met. Lenya watched it and, then packed up some unpublished and little known songs by Weill, and gave them to Stratas, saying to Stratas that nobody sings Weill's music like you do and you should have these. The result was an album of 14 of these songs sung by Stratas, and this week we have several of them for you. Later in the hour we'll have Lotte Lenya herself singing a few of Weill's songs, and Weill will try his hand at his own music as well.
