The Vestige is the first fruit of a new intergenerational collaboration between Giuseppe Ielasi, a quietly prolific key contributor to the European experimental music scene for over twenty years, and Jack Sheen, a young composer-conductor-sound artist from Manchester whose recent projects have seen him moving seamlessly from enigmatic chamber music composition and installations to conducting the London Symphony Orchestra.

Their materials and working methods differ significantly, with Ielasi having focussed for many years on electro-acoustic techniques alongside his ongoing commitment to the guitar, and Sheen primarily composing for traditional instruments. More important, though, is what they share: a fascination with what Sheen calls “mysterious, liminal musical material,” using irregular repetition and cyclical forms to create structures at once alive with activity and almost static, as well as a rigorous exploration of spatial diffusion and the interaction of sound event and environment. Working individually with a library of acoustic instrument sounds from Sheen’s recent projects and Ielasi’s guitar, the pair eventually met for several days at Ielasi’s home studio in Monza, sculpting the fourteen pieces that make up The Vestige.

Like Ielasi and Sheen’s solo works, the record shows an exquisite attention to details of sequencing and pacing, the sound palette and compositional approach consistent throughout while each piece asserts its own identity. The twenty-five seconds of the opening piece serve as an entrée into the record’s distinctive world of sound: repeated chirps fluctuate in volume as they move across the stereo spectrum, woven between strangled snatches of string glissando against a backdrop of percussive ticks, long tones, and white noise. Across the remaining thirteen pieces, Ielasi and Sheen sketch further dimensions of the ambiguous space, where distinctions between pitch and noise, repetition and irregularity, electronic and acoustic remain pointedly unclear. As the record’s title suggests, the origins of the sounds we hear have become remote: while at moments we get flashes of timbres and attacks that could come from wind instruments, bowed strings, or prepared guitar, these remain vestigial traces, glimpsed through a veil of shifting white noise textures. These textures are themselves difficult to trace, suggesting artefacts of the recording process, electronic synthesis, amplified room sound, rubbed instruments or objects. The Vestige shows an unusual degree of attention to frequency range as a compositional tool, something it shares with the hyper-subtle variations of Ielasi’s electroacoustic works and the deliberately ‘unbalanced’ midrange-heavy ensemble of Sheen’s Sub. Here, movement between episodes is as much about adding or removing a frequency band as it is about changes in density, harmonic content, or instrumental texture. Tracks are marked by the sudden appearance of subbass or exaggeration of high frequencies in otherwise similar material, contributing to our sense that these fourteen pieces are like different views on a scene that we can never quite see clearly. While calling up a range of past music, from the early works of Rolf Julius to Simha Arom’s recordings of layered polyrhythms embedded in the background sounds of central African villages to the temporal distortions and layered hiss of DJ Screw, the alluring and disconcerting world of The Vestige is entirely its own.
