This static, this noise, is a scratchy, rough-hewn thing, immediately summoning mental images of fuzz-encrusted turntable needles and fingerprint-coated LPs. From an initial listen to Drift, you’d think you’d discovered some ur-drone, some ancient (well, in pop-music terms) album that predates today’s drone-rich ambient-music community not just by decades, but by several significant generations of recording technology.

The former is the Jamaica-born body of studio techniques that put groove-heavy soul music through an echo chamber, elevating percussion elements into vapor trails of hallucinogenic effects. In dub, a simple snare drum can open up like a flower, and rim shot can ricochet like a SuperBall.
The group Diatribes mixes percussion, piano, and software in the interest of sonic exploration. As heard on their recent Insubordinations netlabel release, they take an approach firmly rooted in the clanky, fluid, theoretically rigorous yet sonically elastic techniques of European free improvisation. Witness Cyril Bondi (drums, percussions) and D’Incise (laptop, objects) mixing it up with a pianist (Jacques Demierre on three of the album’s five tracks, Johann Bourquenez on the other two): “Chants Évadés” (
