If Mui's own description of their debut album as "advanced post-rock" was to be extended to their new LP 'Inside a Moving Machine', then may we suggest a fair appraisal would now stand at "first year of their PhD, having taken a semester in jazz multi-instrumentalism post-rock". The recording facia of Fabrizio Tropeano and Stefano D'Inncecco, Mui has undergone some significant overhauls since their first outing; a situation precipitated chiefly by their new living arrangements, with one in Milano and the other Barcelona. Now that's a commute. Opening through 'Singapore', Tropeano and D'Incecco announce their arrival with muted micro-sound rustles and diffused soundscapes, which gradually coalesce into a tender doctrine of shuffling post-rock, before 'Les Enfants Sourient' continues the evolution by upping the digitalis without drowning out the natural elements. A spiritual neighbour to Sheffield's 65daysofstatic, where they bludgeon the listener through some fantastically rugged riffage, Mui prefer to offer a more sedate perspective on the same territory; a stance which pays dividends on the likes of 'Transizione Salentina' and 'Phonemeout'. Etched throughout with an outlook which suggests plenty of time admiring sunsets, 'Inside a Moving Machine' combines its disparate elements into a completely cohesive and organic whole that gracefully reveals more on each and every listen.
