Rosenstolz was a German pop duo from Berlin that was active from 1991 to 2012 and had chart hits in Germany, Austria and Switzerland. The duo consisted of singer AnNa R. and musician Peter Plate, who also occasionally provided vocals. Rosenstolz achieved significant chart success in the second decade of their career, with five of their studio albums going to No. 1 in the German albums chart.
