Whether or not Steve Reich ever imagined that his endlessly coiling rhythmic cycles would someday find a home in pop music, that day has arrived thanks to Cuddle Magic. Certainly not the first pop act to reference Reich’s trigonometric approach, this collective of former New England Conservatory students employs an arsenal of classical techniques within thoroughly hummable tunes. The smooth edges and palatability that define Cuddle Magic’s third and latest album, Info Nympho, suggest a rigorous origami artist’s mentality more than they betray the band’s conservatory background. Unlike so many chamber pop peers, Cuddle Magic places such a high premium on the discipline of songwriting that few (if any) ornate markings stick out. Live, the band disproves Pete Townshend’s long-held adage that volume is power by gripping audiences with mostly soft-to-softer dynamics. Meanwhile, deceptively cheerful-sounding hooks provide cover for images of suicide, hoarding, mentally unbalanced lust and a full gallery of ever-lurking shadows.
