With opening track “Static Orphans” initiating what appears to be an unlikely mix of atmospheric ambiance with more traditional Southern California style shimmer, The Slip successors The Barr Brothers’ sophomore set instantly affirms the fact that they’re more than simply a typical harmony-laden quartet. While some songs bask in a tangle of acoustic guitars—the auspicious sounding “Even the Darkness Has Arms,” in particular—others, like “England” and “Come in the Water,” vary the template, going from a solitary strum to an emphatic and sometimes wordless refrain. Indeed, “Little Lover” finds them toying with gospel, vague Asian influences and spectral sound shifts, all within a single song. Then again, those that require only a modest melody and a gentle embrace will find both in “Valhallas,” “How the Heroine Dies” and “Please Let Me Let It Go.” A product of both invention and intuition, the appropriately dubbed Sleeping Operator isn’t anything less than a dazzling delight.
