Philharmonie Köln, Cologne. Claude Debussy's symphonic sketches for orchestra known collectively as 'La Mer' evoke a richly varied vision of the sea. The first part ('De l'aube á midi sur la mer') calls up a morning and afternoon at sea, the second ('Jeux de vagues') echoes the play of the waves, and the third and final part ('Dialogue du vent et de la mer') conjures the communing voices of wind and waves. Debussy knew his sea, the Mediterranean, intimately both from childhood visits to Cannes and from his Italian travels later in life.
