The fourth studio album from Mogwai, 2003’s Happy Songs For Happy People is compact – just over 40 minutes – and extraordinarily skillful at sucking you in. The big crescendos don’t come after long passages of quiet, they grow organically and stealthily. The metal power, the hardcore methodology, the pastoral prettiness are hard to separate any more. Rather, they exist in a state of grace that’s moving and inspiring and all those other vague emotions music regularly promises, but rarely delivers.
