With PULSATIONS [BITUMEN], the Swiss composer-performer Marcel Zaes sets out to redefine the conventional concert performance. He presents a transcontinental music project which is a fusion of electronic and classical sound. PULSATIONS [BITUMEN] presents the least featured of all string instruments, the viola, with four exceptional players, and extends the viola’s sound with generative digital technologies that render the performance a live-sampling aesthetic. PULSATIONS [BITUMEN] is the result of Zaes’ typical compositional practice which interweaves the instruments’ voices with pure sine wave tones and mathematical grids to generate abstract pulsations. The result is a groovy, yet minimalist sonic world.

For this work, Zaes introduces a novel graphic notation system that is imperfect and solely capable of displaying a specific kind of rhythmic pattern. This notation system emphasizes musical parameters that are particularly important for PULSATIONS [BITUMEN] such as grid-based loops, signal-to-noise ratios and dynamic envelopes, while neglecting other, more classical compositional elements.

The title part ‘BITUMEN’ stands for asphalt and emphasizes the interaction between the digital algorithm and the violists: machine-like regularity meets with natural irregularities to form a techno-organic surface.

Performance duration: 65 min
