Tool - Undertow -2019- -flac 24-96- ★ Authentic
You won’t hear a $50 difference on earbuds. But on a proper DAC and open-back headphones or floor-standing speakers, the album feels uncompressed for the first time. The original CD felt like a JPEG saved at 80% quality. This 24/96 FLAC is the RAW file—messier, heavier, and more honest.
The 96 kHz sampling rate also captures the transient attack of Danny Carey’s cymbals and Maynard James Keenan’s sharp inhalations (a signature vocal technique) with a more natural decay. The Low End: The most immediate improvement. Paul D’Amour’s bass on Undertow is often overlooked in favor of Justin Chancellor’s later work. In 24/96, the intro to “Intolerance” is revelatory. The bass string noise—the gritty friction of finger on nickel-wound steel—is palpable. It’s not boosted, but it’s articulated . The subsonic rumble during the quiet bridge of “Prison Sex” is no longer a suggestion; it’s a pressure wave.
The biggest mixed bag. The 24/96 transfer is merciless. Maynard’s whisper-to-scream dynamics on “Swamp Song” are startling. You hear the saliva in his mouth before the roar. For fans, it’s immersive. For casual listeners, it might be too intimate, exposing the raw, un-autotuned human effort. The Verdict: Essential or Overkill? For the Audiophile: This is a reference-grade transfer of a non-reference-grade recording. And that’s its genius. Most hi-res releases are of pristine, sterile jazz or classical. Undertow in 24/96 proves that high resolution can serve ugly music. The increased dynamic range finally does justice to the album’s quiet/loud architecture. Tool - Undertow -2019- -FLAC 24-96-
This is where the format either wins or loses you. Adam Jones’ guitar tone is famously mid-forward and harsh—a cranked Marshall with a flanger. In standard resolution, this can fatigue. In 24/96, the harshness is re-contextualized as texture . You can hear the amp’s speaker cone struggling. The feedback on “Sober” isn’t a wash of noise; you can trace its harmonic evolution. The format refuses to smooth over the rough edges. It reveals them.
Fast forward to 2019. The hi-res digital revolution has come for the grunge and post-metal catalog. The question isn’t whether Undertow sounds different in 24/96—it’s whether the format’s pristine clarity enhances or neuters the album’s inherent ugliness. The leap from CD-standard (16/44.1) to 24/96 is not about hearing up to 48 kHz (you can’t). It’s about dynamic range and noise floor . 24-bit allows for 144 dB of dynamic range versus 96 dB on CD. For a band like Tool, who weaponize the contrast between near-silence and crushing volume, this is critical. You won’t hear a $50 difference on earbuds
Artist: Tool Album: Undertow Release Date (Original): April 6, 1993 Release Date (This Edition): 2019 Format: FLAC 24-bit / 96 kHz (Digital Download / HDtracks, Qobuz, etc.) Mastering Source: Likely remastered from the original analog tapes for the 2019 digital reissue campaign. The Context When Undertow burst out of the early ‘90s L.A. scene, it felt like a physical object—dense, humid, and angry. It was the antithesis of the polished hair metal that preceded it. Produced by Sylvia Massy and the band themselves, the album’s sonic signature was one of claustrophobic space: dry, lurching guitars, a bass tone that slithered rather than thumped, and drums that sounded like they were recorded in a concrete bunker.
This is not a remix. Don’t expect Lateralus -era low-end punch. The bass still sits below the guitars. The snare still sounds like a gunshot in a tiled room. What the 2019 24/96 release offers is a wider window into the original analog master tape. Final Score: 4.5/5 Deducting half a point only because the source material’s intentional murkiness will still frustrate those seeking modern metal polish. For everyone else: This is the definitive digital version of a landmark album. Turn it up until the distortion hurts. This 24/96 FLAC is the RAW file—messier, heavier,
A masterclass. The intro to “Crawl Away” is the test track. The hi-hat sizzle has air without sibilance. The kick drum, which sounded like a wet cardboard box on some original pressings, now has a defined, short decay. The toms in the chorus of “Undertow” (the title track) roll with a woody thud that carries spatial information—you can hear the room around the kit.
