Reaching a tenth album is usually the moment a band either coasts or takes stock, and Insomnium chose the second path. Three years after Anno 1696 closed a stretch of sweeping historical storytelling, the Finnish veterans turn inward on Netherworlds, trading chronicles of the past for mortality, memory and the fleeting nature of life seen through older eyes. It is also the full-length debut of guitarist Tomy Laisto, who joins Markus Vanhala and Ville Friman in a three-guitar front line. Friman describes the approach as a “Best Of” philosophy, and that phrase is the best key to the record: this is Insomnium consciously gathering its own trademarks, then asking how far a familiar sound can still be pushed.
The descent begins with something the band had never done, a cover. “The Cold Song”, adapted from Henry Purcell‘s centuries-old piece, lasts just 2:20 and works as a doorway, chilly and theatrical, before “Shadowlife” lets the melodic death metal engine roar. “Remembrance” and “Gleam in the Black” keep the pace brisk, with Niilo Sevänen‘s cavernous growls set against the clean vocals shared by the three guitarists, and early reviewers have heard a Gothenburg accent in the latter, a nod to Dark Tranquility. What matters is the balance. The riffs are heavy, yet each song leaves room for a melody that lingers like mist over water, which is exactly where this band has always done its best work.
The album’s center of gravity is “The Hour Grows Late”. At 8:02 it is the longest track, and it brings in Tomi Joutsen, Tomi Koivusaari and Santeri Kallio of Amorphis, a meeting of two pillars of Finnish melancholy that feels earned rather than ornamental. Around it, “Arch of the Sky” draws on the Sámi worldview and the eternal cycle of life, stretching to 6:15 with a skyward sweep, while “Pathways of the Night” and “Ethereal Sleep” slow the tempo into doom-tinged territory, the latter shifting between delicate passages and dense, heavy ones. Drummer Markus Hirvonen deserves credit here, because his playing stays thunderous without ever flattening the subtler moments.
The closing stretch is where the record earns its emotional weight. “The Banished”, which Laisto brought to the band as a crushing demo, is the fiercest song on the album, and it proves the newcomer is more than a clever addition. Then “Journey’s End”, nearly seven minutes long, arrives at what Sevänen calls the inn of death, and finds peace there instead of terror. Lyrically, Sevänen drew on classic Finnish and English poetry, and the shift from epic history to private memory gives the album a more intimate voice. Miiro Varjus produced, Jens Bogren and Tony Lindgren mixed and mastered at Fascination Street Studios, and the cover painting by Travis Smith, a first for the band, matches the music’s bleak beauty. If there is a fair complaint, it is that some of the middle songs lean on familiar gestures and trade bold new ideas for comfort.
Insomnium knows exactly what its audience loves, and the album delivers it with craft, restraint and a touch of dark humor, starting with a song about freezing to death. The new twists are modest, the cover and the Amorphis collaboration being the boldest, but they are enough to keep the formula from going stale. It does not rewrite the band’s story, though it adds a chapter that is richer and more personal than most, and it should please anyone who has followed the group from its earliest years.
My favorite tracks are “The Hour Grows Late”, “Arch of the Sky” and “Journey’s End”. The first is the most ambitious, the second is the one that opens up the sound, and the last is the right way to say goodbye. Worth noting too: the deluxe artbook edition adds three bonus tracks recorded in the same sessions, which the band describes as the encore after the main performance.
