The audacious challenge of marrying the Schoenberg of 1912 to the Berlin nights of the 1930s imposes the feeling not of kinship, but of proximity, the two sides of the same night. . . It is from the side that one enters the Grand Theatre in the hall to the staircase where the spectators are waiting. . . Top hat, black suit. . . Julia Migenes comes along and performs some of the most popular songs in the Berlin's cabarets of the 1930s, including the revue Alles Schwindel

The audience is then invited to enter into the auditorium, where some spectators find themselves on stage, facing each other, to better restore the proximity and intimacy of the cabaret. At the front of the stage, strongly raised to mark a slope, the setting is a complex moving light installation ; spread out stakes, arranged like a small path. On these stakes, light balls vibrate, turn on and off interactively by reacting to the voice.
