Natural Information Society: Perseverance Flow Album Review – Warungku Terkini

In the same way that a diamond’s symmetrical shine is both easy to admire and requires an eyepiece to appreciate in full, Perseverance Flow’s charm is shaped by the tiny variations built into the score. Once the theme is established and allowed to settle, harmonium player Lisa Alvarado flips her pattern, playing a palindrome of the simple rise-and-fall melody. The shift is so smooth it can take a moment to notice it’s happened, and even then you might second-guess the extent of the change. Drummer Mikel Patrick Avery loosens his percussion a few minutes later, playing something that sounds like pebbles sloshing in a plastic bucket. The soft shuffle is soon absorbed—whether actually or just by a kind of aural illusion—into the original pattern. Abrams anchors the sound with his Moroccan guembri, occasionally halting the steady limp of the primary line to tie a fluid knot without losing a step.

While it’s not unusual for repetition to turn a musical phrase inside out, similar to the way a word loses its meaning once you’ve said it a few times, Perseverance Flow’s emotional register stays constant. The phrases gradually begin to lengthen—at one point, Alvarado’s harmonium sounds more like an accordion playing a Cajun song in slow-mo—which gives the piece enough momentum to stay grounded. At no point does it even glance in the direction of chaos; you could probably thread a needle with the sound wave. Around the 19-minute mark, the entire ensemble pulls up together in a way that suggests a vamp, then immediately falls back into the pattern without anyone losing their place. It’s such a weird little thrill that, if you’re properly locked in, it feels like peaking in sync with a 2 a.m. bass drop.

While the instrumentation wouldn’t be out of place at your local roots festival, the dance music influence on Perseverance Flow is undeniable. Abrams’ frequent switches and intertwined notes mimic the braided bass hits and glitchy rhythms of footwork without ever leaving the aesthetic context of gnawa. Little clap-back rhythms pop up occasionally. At one point, something that sounds like a bag of shells being dropped on a snare drum introduces a new back-and-forth to the theme that matches the harmonium and brings the piece’s shuffle closer to something like hip-hop. It’s a canny way of making sure the listener’s body stays tuned in to what could easily become cerebral; you will not nod your head more insistently to a piece of experimental music this year.
