Welcome to the sound of clicking heels, the spectacle of bodies responding to sweeping rhythms. The German choreographer and step-dance artist Thomas Marek presents «Orchestra». This is a fast-moving concert based on dance, of choreography responding to sound. Ten dancers move fluidly from elaborate arrangements to improvisation. Traditional tap dance patterns are opened up. Full-bodied dance and electronic music are melded together. This dancing «Orchestra» is sensually and poetically entwined with its own instrument – the dance floor. (ron)
