In the exhibition "Silent Piece" works of the French photographer Marion Kalter (*1951) are presented. Over the quarter of a century she has created portraits of musicians, music theorists, philosophers, among others, of Francis Bacon, Roland Barthes, Pierre Boulez, William S. Burroughs, John Cage, Jacques Derrida, Mauricio Kagel, Claude Levi-Strauss, Karlheinz Stockhausen, Susan Sontag, Wolfgang Rihm and Iannis Xenakis.

"To browse through the album of Marion Kalter is much more than to look at portraits of musicians, maybe still lifes (instruments or scores), it is to enter in deep contact with the impenetrable world of music and musicians." 
(Pierre Boulez)

The film "À la croisée des chemins de Pierre Boulez" (2013) directed by Sacha Goldman was produced to accompany the exhibition. It shows Boulez with the portraits by Marion Kalter, which evoke memories of Pierre Boulez on his companions and the development of New Music.
