Aachen, Düsseldorf, Kleve, Köln and Lüttich: these were not only important rich, residential or cathedral cities but also centers of 16th century music culture: the century of the Renaissance. The Rhenisch music culture of this time was long in the shadow of the big Flemish musicians of the 15th and 16th centuries, who were working at the important courts of the time. The region's music was, however, long considered as less important when measured against the ideals of the Italian Renaissance, and it is only perceived afresh and stronger today as worthy, independent artistic expression. The LVR Country Museum in Bonn showed the historical art and culture Renaissance Exhibition on the Rhein from September 2010 to February 2011, which presented the Renaissance as an independent era for the Rhein lands. The comprehensive approach of the exhibition naturally incorporated the music culture of the lands along the Rhein in the 16th century. In this context, the present CD of the vocal ensemble Singer Pur came into being. Intensive research led the performers and the supporting scientists as well to previously undiscovered musical treasures that can now be heard for the first time.
