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.

"Mr Beast" is the band's fifth studio album and, as the title suggests, sees them returning to their first, true love - Rock with a capital "R" - after using a softer palette with more varied instrumentation for album number three ("Rock Action") and delivering a balanced summary of their work to date with 2003's "Happy Songs For Happy People". Mogwai of course, make their own rules in order to break them, so, alongside huge blocks of thrillingly implacable guitar noise, "Mr Beast" features exquisitely poignant piano passages (most of them played by keyboardist/guitarist/vocalist Barry Burns) and great, limpid spaces.
