"Daemonic n0!se from the wrong don, Russell Haswell; conjuring 32 minutes of mutant scree and squabble - some of his most fuqqed-up since his Conceptual n0!se LP. Constitutional captures Haswell at his most lacquer-buckling and invasive, triggering a seamlessly chaotic and endothermic chain reaction of sounds that seemingly suck in all energy around them to a null point between the eyes. As with all Russell’s gear, it’s rendered in intricate free-hand guided by a fine tuned improvisational meter, one which appears to react to the smallest fluctuations in Russell’s own body temperature, psychic energy and the acidity of last season’s apple crop, which all serve to underline the piece’s narrative logic with an wildly, perfectly unpredictable nature that’s long been at the core of his practice. Scaled from claustrophobically microscopic and lower case to pranging hard-stops , this is one of Haswell’s most dynamic, discombobulating demonstrations, right up there with his most chewy and satisfyingly uncomfortable work" (Boomkat).
