These days - when membership of the rock army can be symbolised by the simple purchase of a Ramones T-shirt - dedication has become a debased currency, subject to the hyper-inflationary dictates of fashion. Raw recruits sign up for the short term, soon surrendering their affections to whichever sexy "scene" might spring up next. Unswerving commitment to rock's righteous cause is rare; it demands a troop of seriously single-minded dudes with their collective heart and soul fixed on one goal - to bring the noise. Scottish five piece Mogwai formed in 1995 and debuted a year later with the single "Tuner/Lower", released on their own Rock Action label. They've since gone on to develop their distinctive style of apocalyptic, yet deeply humanised noise across four albums, establishing the transcendentally effective quiet-loud/quiet-loud dynamic as their very own and spawning a generation of imitators. Usually tagged a post-rock band because of their slow-build, instrumental workouts and the neo-classical majesty of their more ambitious songs, Mogwai are rather a bunch of a-rockers, drawn to whatever serves their cause - be it the stripped-down delicacy of Erik Satie or the boiling rage of Big Black. Mix light and dark together, Mogwai understand, and you make magic.
