Fischer-Dieskau was unquestionably the finest German baritone of the post WWII world. His interpretations of the core German vocal repertoire, from Bach to Schubert to Mahler, have long been regarded as definitive.
Interestingly, Fischer-Dieskau was drafted into the Wehrmacht in 1943. He served on the Russian and Italian fronts, and was held by American forces as a prisoner of war from 1945 to 1947. In POW camps, he put on recitals of classic German art-songs for nostalgic German soldiers.
I never had the opportunity of hearing Fischer-Dieskau perform live, but he was certainly a favorite of my uncle, from whom I've inherited a number of his beautiful "lieder" recordings.
This is Fischer-Dieskau singing Richard Strauss's "Morgen," ("Tomorrow"), recorded in 1974. It's set to verse by the Scottish-German poet John Henry Mackay.
And tomorrow the sun will shine again
And on the way which I shall follow
She will again unite us lucky ones
As all around us the earth breathes in the sun
Slowly, silently, we will climb down
To the wide beach and the blue waves
In silence, we will look in each other's eyes
And the mute stillness of happiness will sink upon us
