The Quatuor pour la fin du Temps is one of the most fascinating works of the twentieth century. Its ability to embody many of the historical traumas and cultural revolutions that have influenced our world right down to the present day is unique. Complex rhythms, refined polyphony and passages of the most extreme sweetness place us before an existential question: how to create a religious and avant-garde work in a Nazi prisoner-of-war camp? Contrasts of writing, mixture of timbres and expressive power are also the prerogative of Thomas Adès’ work, Court Studies (2005) which completes this program.
