slenderbodies is aptly named; the physiques of the California-based duo aside, its sound conjures up images of waifs swaying in the wind, a soft interplay of light and waves crashing in slow motion. Though perhaps that last image is planted, since slenderbodies likens its second release, the EP Fabulist (Majestic Casual Records, 2017), to "floating across the ocean of the mind." This year, the ethereal duo doubled down on that vibe with Fabulist: Extended (self-released, 2018), a new EP of what it calls "short stories"—and what we might call pulsing, electronic whispers—that it will bring to the Knitting Factory on Thursday, Sept. 6. In Boise, slenderbodies is the special guest of the quirky German folk duo Milky Chance, but following a list of tour dates together in September, slenderbodies will strike out on its own to headline shows in the American south and east. Catch the two groups together while you can.
