Dance is more than movement to music. Dance is passion and pure lust for life. Celebrations call for dancing. That was as true in the palaces and the taverns of the 18th century as it is today in the techno temples of the new era. This is the surging river that ECHO-Klassik winners Spark have set out to bridge in their project "On the Dancefloor". The Classical Band throws an arch from the spirited ballet music of Wolfgang Amadeus Mozart to the chamber techno penned by contemporary composer Sebastian Bartmann, finding that two seemingly contrasting worlds actually fit very well together.
