Primal Scream's recent output has been blighted by an overreliance on their default setting of "ersatz Stones". Thankfully their 10th album finds them stepping out of their comfort zone again: nine-minute opener 2013 is a bold mix of shrieking sax, Kevin Shields's guitar noise and state-of-the-nation rhetoric. The more restrained moments are equally unpredictable and equally well judged. Of course, Bobby Gillespie's lyrics are still largely embarrassing, thanks to a propensity for insurrectionary non sequiturs that are big on abstract nouns but shakier on sense. But this is still their most exhilarating album since 2000's superlative Xtrmntr.
