El Silenci Dabans de Bach (Die Stille vor Bach) looks at the profound relationship between image and music where the latter is not merely conceived as subsidiary to the image but as a subject of the narration in its own right. It springs from a previously defined musical structure, and the soundtrack feeds on works by J.S. Bach and two of Felix Mendelssohn's sonatas; a promenade through the 18th, 19th, 20th and 21st centuries led by the hand of J.S. Bach.
