Christian Wallumrød’s "Percolation" (Sofa, 2025) is the kind of record that tiptoes into your ear rather than barging through the door. A pianist who has made a career out of making silence feel like an instrument in its own right, Wallumrød here seems to let sound drip and trickle, as though testing how little is needed to make music happen. It’s both modest and mischievous: hesitant notes, awkward stumbles, ghostly synths, even an autoharp drifting in like a curious stranger. And yet, amid the false starts and cracked edges, there’s melody - sometimes fragile as a folksong remembered in fragments, sometimes slyly grinning like a Monk riff gone Nordic.

What makes "Percolation" so magnetic is its refusal to choose between beauty and oddity. “Ny gitar” and “The sing” could almost be hymns, stripped to their bones, while “Higher than your gluteus” throws us into a swampy New Orleans groove before handing the reins to a squelchy acid-house beat that sounds like someone spilled coffee on the sequencer. It’s playful, a little irreverent, but also tender: music that doesn’t aim for perfection so much as presence.

Across his long and uncategorizable career - dancing between jazz, folk, new music, improvisation, and whatever else refuses to be neatly boxed - Wallumrød has built a language where silence and noise, virtuosity and clumsiness, history and future all keep each other in check. "Percolation" distills that language into its purest essence, neither a departure nor a repetition, but a refinement: a filtering, a trickling through. Like the title suggests, the record seeps slowly into you, until you realize you’re humming along to something that may or may not be a melody, but is definitely Christian Wallumrød.
