From a Mogwai gig review at The Guardian:
Not enough is written about the sensual pleasure of being bathed in noise. There’s probably a good reason for this. Pretension is a constant danger. It’s hard enough to articulate what rock music actually sounds and feels like when there are lyrics to analyse and themes to play with. When – as in the case of Mogwai, a largely instrumental Glaswegian five-piece – there are few words, just sinuous guitar lines erupting into ear-splitting volume, the risk of ending up in Pseud’s Corner, waffling on about cathedrals of sound, is high.
But here goes. Being bathed in a wash of deafening guitar noise is lovely.
It really is that simple. Lovely. :)
