With Gizicki, Vienna-based duo Rotterdam—Susanne Amann (cello, electronics) and Michael Klauser (guitar, tuba, electronics)—push their “magic formula” of difference and repetition further. Mathematical precision meets volatile instrumental interplay: monotone dances, mantra-like recitatives, and undulating sound clusters feel anticlimactic, mechanical, and deliberately de-emotionalized—ceremonial music for a machine cult. Yet the loops’ hypnotic pull steadily opens the ear. What first seems mechanical reveals a living spectrum of tone and dynamics in these live acoustic takes: subtle strums, bow strokes, taps and plucks, and overtone bloom sustain a finely tuned tension.
