Rosenstolz (German pronunciation: ) was a German pop duo from Berlin that was active between 1991 and 2012 and had chart hits in Germany, Austria and Switzerland. The duo consisted of singer AnNa R. and musician Peter Plate, who occasionally provided vocals. Rosenstolz achieved major chart success after the nineties, with five studio albums going to No. 1 in the German albums chart. Although the duo split up to pursue separate music careers, they left open the possibility of a future reunion. Rosenstolz's music was described by critics as containing elements of various genres, including pop and chanson. However, comparisons with schlager were strongly disputed by the duo, who defined themselves simply as a pop group. Rosenstolz's repertoire included ballads and quirky pop songs, though later years saw the duo eschewing their quirky side. Common themes in the songs written by Rosenstolz were sex, love and emotions.
