Already a fan? Relax. It's one of their best. For the rest of you -- if you've been on the fence about the Boys, Fundamental could be the album to bring you into the fold. "Indefinite Leave to Remain" is the best place to start, as it takes elements from all aspects of their sound: big string arrangements, beaty, plinky synths, wry lyrics sung slightly bored and always an underlying warmth, provided, in this case, by a brass band.
