Accompanied by Patricia Kopatchinskaja, the soloists of the Ensemble Intercontemporain offer us an anthology of the dialogues that today’s composers are forging with Bach’s work: Anton Webern orchestrating the Ricercar a 6 voci, György Kurtag and his transcriptions for piano four hands, George Crumb and his Black Angels quartet, while Luigi Nono and Salvatore Sciarrino refer to it in their works for violin, alone or in duet.
