Johann Carl Gottfried Loewe, usually called Carl Loewe, was a German composer, tenor singer and conductor. In his lifetime, his songs ("Balladen") were well enough known for some to call him the "Schubert of North Germany", and Hugo Wolf came to admire his work. He is less known today, but his ballads and songs, which number over 400, are occasionally performed.

"Erlkönig" is a poem by Johann Wolfgang von Goethe. It depicts the death of a child assailed by a supernatural being, the Erlking, a king of the fairies. It was originally written by Goethe as part of a 1782 Singspiel, Die Fischerin.
