Temples’ second album brings increased purpose to the heady psychedelia of their debut, Sun Structures. Synths add playful menace to the dynamic grooves of “Certainty” and “Mystery of Pop,” and whether the quartet dabble in freak-folk (“Oh the Saviour”) or motorik glam (“Roman God-Like Man”), insistent melodies are always sewn in. With its euphoric chorus, the widescreen “Strange or Be Forgotten” could have been written to fill arenas. On this evidence, that wouldn’t be presumptuous.
