Carl Heins

Heins' pieces show a special pianoesque ability to fashion pretty melodies picturesquely in the salon style of the time.

He composed the song 'Zwei Dunkle Augen', which was recorded by the tenor Fritz Wunderlich.

Stylistically his music is similar to that of his older compatriot Carl Bohm.

Robert Leonhardt, an operatic baritone who sang with the New York Metropolitan Opera company between 1913 and 1922, made numerous recordings for many major record labels, both in Europe and in the United States.

An early recording he made on Gramophone 42325 with matrix number 1113B[54] was "Zwei dunkle Augen" by Carl Heins.
