Rheingold is the 11th studio album by German heavy metal band Grave Digger. It is a concept album based on Richard Wagner's The Ring of the Nibelung. The album was released in 2003. Many lines of the lyrics are quoted or paraphrased from (an English translation of) Wagner. The music also has occasional references to Wagner, the most obvious one perhaps being the intro to the song "Dragon", which is the "Siegfried's Horn Call" leitmotif.
