Changing your sound must be equal parts thrilling and intimidating. On the one hand, it’s an opportunity to explore and flex your creative muscles, to see what else you can do. On the other hand, it may alienate your listeners, but more simply, it may just be unsuccessful. This is the crossroads at which we find Kansas-based Thaumaturgy. While their debut, Tenebrous Oblations, was a cavernous voyage through Mortiferum’s lightless catacombs, sophomore effort Pestilential Hymns, is a notable departure from that sound. Founder KT has brought on the equally mysterious TG and DS to realize this new sound. Is this evolution a confident step forward or an ill-conceived stumble?

Thaumaturgy’s sophomore effort is indeed a big change from their debut, but it’s got the same bones. The reverberous cobwebs that swaddled Tenebrous Oblations may be gone, but the murky, serpentine structures remain, often taking on a blackened char in the clearer production. “The Oncologist’s Hymn” and “Awaken Ares” showcase this well, employing textures that evoke SVRM or Wolves in the Throne Room, although more sinuous than Cascadian. Pestilential Hymns further departs from its predecessor with new vocalist, TG. KT still provides deep, cavernous roars as a backing vocalist, but TG looks to Death and Pestilence for inspiration, employing more howl than scream or growl. This would be concerning were it not for the added classic death/thrash riffcraft of those forebearers that complements TG’s performance. The last major change in Thaumaturgy’s sound is the inclusion of synths, most often used to augment or reinforce the atmosphere fostered by their newly blackened edge (“Plague Ritual,” “Neuroticism Triumphant”).

The deployment of these new elements on Pestilential Hymns is a bit of a mixed bag. Riffs and leads seared black bring a compelling gothic tone to the album that pairs well with that classic death metal sound (“Forced March”). Thaumaturgy’s two main styles—classic death and cavernous death—largely alternate as TG and KT pass the mic, creating a shifting landscape that keeps me invested through Pestilential Hymns’ 46-minute runtime. This separated approach does, however, encourage comparison between such regimented styles and passages, and I tend to gravitate toward and appreciate one over the other. An approach more melting pot and less mosaic may have alleviated this pain point. In a rare attempt at a more cohesive whole, “Entropic Hegemony” features a great deal of interplay between vocalists, but the Beastie Boys call-and-response style employed can be distracting.

Each element of Thaumaturgy’s new sound holds its own in isolation, but solid combination or incorporation is an area where the band could improve. Synths sprinkled throughout Pestilential Hymns do succeed in establishing atmosphere and evoking intended emotions, but only when embedded within tracks rather than serving as outros to them. Throughout the album, there’s a combined four minutes of synthy outros that don’t do much more than delay the oncoming track or blunt a strong finish (“The Oncologist’s Hymn,” “Awaken Ares,” “Forced March”). Add a handful of instrumental passages that linger overlong (“The Shadow Approaches,” “Plague Ritual”), and bloat and pacing become real issues. This is exacerbated by interlude “An Ignominious End.” I like the atmosphere it builds—I immediately thought of Evoken’s exhausted shuffles—but at 2:30 and as the penultimate track, it kills any momentum leading into the album’s end. Smaller doses of this energy could have been incorporated into the meat of proper tracks to better effect.

Pestilential Hymns feels like a step back from Thaumaturgy’s debut, but one made out of exploration and experimentation. It’s a dip in cohesion, not a dip in quality. Everything here succeeds individually, and the majority does so holistically as well. But there are a few fundamentals—pacing, synthesis, bloat—that this broadened focus neglects. That said, Pestilential Hymns is still a fun listen and shows much promise toward a more unified future vision. My complaints seem easily attributable to growing pains and self-discovery, which, of all possible faults, are among the more commendable ones. And if there’s a choice between taking risks and retreading solid ground, I’ll support evolution every time.
