The 50-minute work for 3 vibraphones and 20-channel 1-bit electronics is performed by the dynamic French group, ensemble 0, who return to Erased Tapes following their 2023 collaboration with Peter Broderick. Perichs music spans the electronic/classical divide, with explorations that pair string instruments, piano, organ, and other acoustic instrumentation with custom-built 1-bit electronics. Open Symmetry pares the ensemble down to just 3 musicians playing the resonant metal bars of 3 vibraphones accompanied with a glistening ensemble of 20 speakers, each playing their own separate musical part of the composition.
