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. The title Giddy Skelter alludes to both Gimme Shelter, the infamous documentary about the Rolling Stones’ disastrous Altamont free concert, and the Manson Family’s Helter Skelter scenario. But none of this is an homage to a bygone era. And there’s another dimension to the title: It can be interpreted alchemically, combining two of the most popular songs in rock history — “Gimme Shelter” and “Helter Skelter” — both of which have sinister associations that give them greater gravity. 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.
