Temples’ debut LP, 2014’s Sun Structures, was a paean to 1960s psychedelia, brimming with Summer of Love guitar effects and Lennon-esque melodies. The British quartet earned both adoration and venom for that retro worship, pegged by critics as a “next big thing” and simultaneously as a backward-looking bore. Their self-produced sequel, Volcano, is equally indebted to the past—just more of the past, as their vintage psych-pop is laced with massive new-wave synthesizers. But, after a while, the scattered reference points start to blur into the band’s own cherry-picked sonic collage. “Roman Godlike Man” veers from Abbey Road riffage to a power-pop-chorus Ric Ocasek would’ve killed for in 1978; swooning closer “Strange or Be Forgotten” sounds like Tame Impala soundtracking a high-school prom slow dance from a John Hughes film. Even better are tracks that combine past and future: “Certainty” and “I Wanna Be Your Mirror” both showcase the band’s newfound emphasis on the low-end, with bass and lead synths buzzing over battering ram-drum grooves. Temples sound awkward and unnatural when they lapse into hazy reverb atmosphere (“How Would You Like to Go”). But when frontman James Bagshaw sinks his teeth into a meaty hook, few of their psychedelic peers—or forefathers, for that matter—can approach their orbit.
