"Fuchs" (the nickname of the singer/guitarist/composer) is German for "fox".

'Die Apokalyptischen Reiter' can be translated in English to 'Horsemen of the Apocalypse'.
The Four Horsemen of the Apocalypse are mentioned in the Bible in chapter six of the Book of Revelation. The four horsemen are traditionally named Pestilence, War, Famine, and Death. However, this is slightly at odds with the conventional interpretation of the Bible, which actually only directly names the fourth: "Death".
