Stan Oliver

Kieth Engen was an American operatic bass who was a member of Munich's Bavarian State Opera for decades. Although his career was based in Munich, he appeared internationally as a guest singer at major opera houses and festivals and performed and recorded many of Bach's Passion oratorios and cantatas, primarily with the conductor Karl Richter. He was born Keith Sheldon Engen in Frazee, Minnesota, and died in Murnau am Staffelsee, Germany at the age of 79. He was given the title of Kammersänger in 1962 and was a recipient of the Bavarian Order of Merit. In the mid-1950s he also had a brief parallel career as a pop singer under the pseudonym Stan Oliver.
