The new Broadcast album, in the company of Julian House’s Focus Group, has proved to be one of those records that resist, in some way, being written about. Perhaps it may be something to do with how “Broadcast And The Focus Group Investigate Witch Cults Of The Radio Age” is a slippery, fragmentary listen; a collage of 23 disjointed, often dislocated snippets that feel as if they’ve been harvested from a dusty collection of neglected old soundtracks. An album that slips in and out of focus and of your attention, sneaking up when you least expect it.
