Tim Kinsella and Jenny Pulse have spent years making thoughtful and unpredictable art, whether musically as Joan of Arc or Spa Moans, or under their given names as writers and visual artists. On Giddy Skelter, their debut album as the unadorned “Tim Kinsella and Jenny Pulse,” they once again take an unexpected turn, but aim for something more direct. They’ve crafted a swirling, past-future, future-past, sorta-rock, collage-rock, melange borne from the confined anxiety of the pandemic. It’s a full-length undeniably of its moment, rich with musical references while radiating a visionary path forward. To assemble Giddy Skelter, Kinsella and Pulse aggressively culled their tracklist until they had a lean and impactful 11 songs, unlike anything either musician has released before. Opening track “Unblock Obstacles” chugs along on a three-chord riff and dubbed-out drums before venturing into a hypnotic, feedback-filled drone that channels pre-Loveless My Bloody Valentine. “Over and Over” imagines a world where Slowdive or Lush collaborated with Prefuse 73. On “Nena,” one minute features loops of classical piano, the next Spacemen 3-style psychedelic drone, and the next contemporary R&B. The majority of songs on Giddy Skelter foreground Pulse’s yearning, ethereal vocals, giving the music a distinctly feminine overtone. Sometimes the thing that makes great rock n’ roll is the ineffable and the intangible, something you can only describe as alchemy; other times it’s the rigors of process. On Kinsella and Pulse’s Giddy Skelter, it’s both — and it sounds unlike anything else you’ll hear this year.
