Horizontal shift, features the international trio, from Germany and U.S., of Birgit Ulher, Carol Genetti, and Eric Leonardson. The CD consists of a live performance recorded in 2018 at Elastic Arts in Chicago. Having known each other since the late 1990s, it wasn’t until early 2018 that Ulher, Leonardson and Genetti were able to perform as a trio at Elastic Arts in Chicago. All three are seasoned performers in their own right — each bringing their distinct palettes in combination to create an improvised music with the microtonal and textural characteristics of sound. Ulher’s extended trumpet with its grainy clicks and multiphonics, Genetti’s abstract vocals with its wordless utterances and and Leonardson’s self-built “Springboard” with its bowed reverberations explore an atmosphere of expressive relationships of sound and silence; deep resonances, subtle microtones, splitting sounds, rough textures and shimmering multiphonics.
