“This isn’t new territory for the band—beginning with 2018’s Modern Meta Physic, Peel Dream Magazine have taken cues from bands like Stereolab and Pram, exploring the ways that rigid, droning repetition can make time feel rubbery. As they snap back into the present, Black sings, ‘Millions of light years, all of them ours.’ The past and future fold into themselves, braided together in perpetuity.” — Dash Lewis, Pitchfork, 4 Sept. 2024
Did you know?
Perpetuity is a “forever” word—not in the sense that it relates to a lifelong relationship (as in “forever home”), but because it concerns the concept of, well, forever. Not only can perpetuity refer to infinite time, aka eternity, but it also has specific legal and financial uses, as for certain arrangements in wills and for annuities that are payable forever, or at least for the foreseeable future. The word ultimately comes from the Latin adjective perpetuus, meaning “continual” or “uninterrupted.” Perpetuus is the ancestor of several additional “forever” words, including the verb perpetuate (“to cause to last indefinitely”) and the adjective perpetual (“continuing forever,” “occurring continually”). A lesser known descendent, perpetuana, is now mostly encountered in historical works, as it refers to a type of durable wool or worsted fabric made in England only from the late 16th through the 18th centuries. Alas, nothing is truly forever.
