Polio

Harsh noise wall (often abbreviated HNW) is an extreme substyle of noise that focuses on producing a monolithic, static "wall" of sound with virtually no perceivable change over long durations. The texture is typically broadband, high-gain, and unrelentingly loud, emphasizing sheer density and timbral grain over dynamics, rhythm, or melody. Aesthetically, HNW tends toward minimalism and austerity: the piece begins and, for the most part, remains the same until it ends. This reduction of musical events is intentional, directing the listener’s attention to micro-level fluctuations in the sound mass, bodily perception, and the temporal experience of endurance. Releases are commonly issued in long-form formats and often feature stark visual presentation and conceptual themes of anonymity, erasure, or anti-performance.

New England experimental refers to the loose, DIY-rooted experimental music ecosystem centered in the U.S. New England region—especially Providence, Rhode Island, and Massachusetts—where noise, free improvisation, art-damaged rock, and psych-folk cross-pollinated in the late 1990s and 2000s. The scene is best known for Providence’s Fort Thunder orbit (Lightning Bolt, Mindflayer) and Western/greater Massachusetts free‑folk collectives (Sunburned Hand of the Man), whose practices fused punk’s energy with exploratory methods, guerrilla performance, cassette culture, and gallery/warehouse spaces. These artists favored visceral drums-and-bass assaults, contact‑mic’d electronics, extended techniques, and long-form improvisation alongside lo‑fi documentation and small-run releases.
