After two interesting but only sporadically great albums, it's heartening to learn that Mogwai have decided to return to their earlier material where their quiet/loud approach was at its most riveting and - ultimately - at its most influential. The scene is set immediately with the angry 'Auto Rock' followed by the even angrier 'Glasgow Mega-Snake'. Whilst these tracks represent the loud side of their sound, though, there's already a sense of ground being re-trodden. 'Acid Food' adds some appropriately psychedelic whimsy but it's only four tracks in, on the gripping 'Travel Is Dangerous', where Mogwai begin to sound vital again and its momentum is retained on 'Friend Of The Night'; one of those achingly melancholic guitar melodies which this Scottish band perfected on 1999's classic 'Come On Die Young' record. It's a thumbs-up too for negotiating the potentially hazardous 'I Chose Horses' with skill and élan; bearing in mind it features a spoken word vocal from a Japanese hardcore act combined with Craig Armstrong's classical piano . So it's another accomplished effort from Mogwai but somehow they seem to becoming less and less important to the music world with each release.
