Chicago-based vocalist Haley Fohr is Circuit des Yeux, a one-woman powerhouse with an operatic voice that dips into hauntingly low registers. It's hard to say whether listening to a Circuit des Yeux song—especially with headphones—is more like stepping into fairyland (the dark, Brothers Grimm kind) or falling down the rabbit hole. Beautiful yet eerie, packed with slightly off-kilter beats and head-tilting lyrics like "stick your head into a paper bag / and see just what you find," Fohr's experimental folk music is as unique as its producer, who once performed from inside an echo chamber dubbed "The Big Black Box" at a German music festival to protest attacks on safe spaces. One listener described Fohr's sound as "the perfect offspring of Kate Bush, Alison Moyet and Annie Lennox," and in a review of her newest album, Reaching for Indigo (Drag City, 2017), Pitchfork called her voice "a singular, transformative instrument." To hear for yourself—and potentially be transformed—snag tickets to her Jan. 25 show.
