Lotte Lenya is just an amazing singer. I love her. Sure, her style seems to be on the dated side, but she was born in 1898, and left us in 1981. She was married to composer Kurt Weill, and is perhaps best known as the Rosa Klebb in From Russia With Love and as a name in a song so dubbed by Bobby Darin and Louis Armstrong while singing Mack The Knife, her husband's best known song. But she was an important singer and performer on the world stage, first in Europe, and eventually in New York. Her work in the Bertold Brecht and Weill musicals Three Penny Opera and The Seven Deadly Sins certainly set the mark for many actresses in decades to come.
Here is a clip of her singing Alabama Song from The Rise & Fall of the City of Mahagonny, another great work by Brecht and Weill.
