Ingurgitating Oblivion

Rivers of Nihil are a Reading, Pennsylvania band who wrote a four-album cycle with one season each, and turned the autumn record into the one everybody names first. Where Owls Know My Name (2018) put a saxophone in the middle of a technical death metal album — three solos and atmospheric passages from Burial in the Sky's Zach Strouse, with cello and trumpet around them — and it landed because the songs were already long, cinematic and keyboard-shaded, with somewhere for a horn to go. Brody Uttley's keys and programming carry that atmosphere; Adam Biggs moved from bass to lead vocals in 2022, and the self-titled 2025 album was written with no dedicated frontman at all. The saxophone stayed, which is the tell: the band deliberately refused to be 'the sax band' and kept using it anyway, as one more colour rather than a gimmick to retire.

Ehnahre is a Boston, Massachusetts experimental extreme metal ensemble formed in 2006 by former Kayo Dot members Ryan McGuire and John Carchia, fusing contemporary classical composition, aleatoric music, and doom/death metal extremity. The group avoids original lyrics, instead setting texts by modernist poets to dense, largely through-composed pieces built from extended technique and free improvisation.

Gorguts is a Canadian extreme-metal band formed in Sherbrooke, Québec in 1989 around founder Luc Lemay, and one of the acts that turned death metal toward dissonant, atonal, structurally complex 'avant-garde' territory (notably on 1998's Obscura and 2013's Colored Sands). Their experimentalism lives inside the death-metal idiom rather than in cross-genre blending, pairing technically demanding writing with harsh, jagged harmony. The reunion lineup drew in New York avant-metal figures Kevin Hufnagel and Colin Marston.

Montreal trio blending sludge and death metal weight with jazz-inflected saxophone, ambient dronescapes, and psychedelic textures across long-form concept albums. Their 2022 record Hivemind unfolds as a continuous sci-fi narrative about first contact with an insectoid hivemind, drawing comparisons to early Mastodon, Dvne, Neurosis, and Oranssi Pazuzu. Formed from the ashes of Montreal band The Wild Hunt in December 2016, the band restructured as a three-piece in January 2021 with all members sharing vocal duties and reaching for non-traditional instrumentation.

Dagtum is a Filipino death metal trio from Pateros formed by veterans of the local extreme-metal underground, including Adam Carlo Along of Legion and brothers Ronaldo Jr. and Ronnel Vivo of Basalt Shrine. Their 2021 debut Revered Decadence (Eastbreath Records) folds dissonant, sludge-thickened death metal into jazz-inflected improvisation and creepy, horror-soundtrack atmosphere, drawing comparisons to Gorguts, Ulcerate and Portal.

Death, formed in Florida in 1983 by guitarist/vocalist Chuck Schuldiner, is the foundational American death metal band - its 1987 debut Scream Bloody Gore is widely cited as one of the genre's first records. Across seven albums Schuldiner, the sole constant member, steered the band from raw, gory death metal toward an increasingly technical and progressive style, culminating in Human (1991), Individual Thought Patterns (1993) and Symbolic (1995). That later era wove jazz-fusion musicianship into extreme metal, drawing on Cynic's Paul Masvidal and Sean Reinert and Steve DiGiorgio's fretless bass. The band ended with Schuldiner's death from brain cancer in 2001.

Dysrhythmia is an instrumental progressive/technical metal trio formed in Philadelphia in 1998 by guitarist Kevin Hufnagel and drummer Jeff Eber, now based in Brooklyn. Bassist Colin Marston — also of Krallice, Behold...The Arctopus, and the reunited Gorguts — joined in 2004, and the band's eight studio albums fuse jazz-inflected chord work, technical/progressive-death riffing, and prog-rock structure into a wordless, largely live-tracked instrumental attack.

A Chicago/Minneapolis improv-death quartet (with members of Zebulon Pike, Celestiial, and Obsequiae) whose albums are single continuous live improvisations rather than composed songs, splicing death metal's blast-and-growl violence with doom lumber, free-jazz harmolodics, and drone-thick ambience. The band cites John Zorn's Naked City and Ornette Coleman's harmolodic concepts as explicit touchstones, assigning time-boxed solo/duo segments to a stopwatch instead of a setlist. 2025's 'Enter the Misanthropocene' pushed further into jazz noodling and grind intensity relative to its drone-heavier 2022 debut.

Sarmat is a New York technical death metal quintet whose 2023 debut Determined to Strike (I, Voidhanger Records) pairs Gorguts-style dissonance with jazz-fusion horn and piano interludes, drawing comparisons to a hybrid of Imperial Triumphant and Weather Report. The record is framed as the first chapter of a three-part interstellar sci-fi concept cycle, and was mastered by Colin Marston at his Menegroth studio. Bassist/pianist guest Steve Blanco doubles as the touring bassist of Imperial Triumphant.

Opeth are a Stockholm band formed in 1990 who spent three decades welding death metal to 1970s progressive rock — Mikael Åkerfeldt growling over one riff and crooning over the next, with acoustic guitar, mellotron and knotty jazz-leaning chord changes given as much room as the heaviness. Steven Wilson's production on Blackwater Park (2001) and the entirely clean, mellotron-soaked Damnation (2003) pushed the prog half to the front, and by Heritage (2011) the growls were gone altogether in favour of jazz rock, Camel and Swedish folk. The Last Will and Testament (2024) brought the death vocals back after sixteen years inside a narrated 1920s will-reading concept record, with Jethro Tull's Ian Anderson on flute and narration. Theirs is the rare case where the experiment became the mainstream success, and the audience followed them into the strange parts anyway.
