A Dark Journey Through Dreams, Grief and Death

Insomnium return to the cold, melancholic sound that made fans fall in love with their music. On their tenth studio album “Netherworlds”, the Finnish melodic death metal band once again explore the darker side of metal, where heavy riffs and haunting melodies go hand in hand.

Released on October 16th, 2026 through Century Media Records “Netherworlds” finds the band looking back toward their classic sound while adding new ideas to the mix. The result is a record built around crushing riffs, haunting melodies, harsh growls and a stronger role for clean vocals.

And there is more going on here than first meets the ear. Behind the album dark atmosphere are real-life losses, an unusual recording process, unexpected tempo changes and a collaboration with three members of Amorphis.

Let’s step into the darkness.

Back to the Melancholy, With a New Bite

Insomnium have built their name on mixing melodic death metal with deep emotion. On “Netherworlds” they return to that familiar territory after the more conceptual direction of Anno 1696.

But this is not simply a trip back to the past.

Guitarist Tomy Laisto makes his first full-length songwriting contribution to the band, bringing a sharper, thrash-inspired bite to the guitars. Meanwhile, clean vocals and more dynamic arrangements give the songs extra room to breathe between the heavier moments.

The album was produced by Miiro Varjus and mastered by Jens Bogren, creating a dense, cinematic sound that balances savage heaviness with the band trademark gloom.

For fans who have followed Insomnium for years, the familiar atmosphere is still there. The difference is in how the band plays with it.

The Cold Story Behind “The Cold Song”

The opening track has a chilling history of its own.

“The Cold Song” is a metal cover of a 17th-century classical piece by English composer Henry Purcell. Guitarist Markus Vanhala explained that the story behind Purcell supposed death made the song a fitting choice for Insomnium bleak musical world.

According to the story, Purcell died of pneumonia after his wife locked him out of their house in freezing weather because he came home late and drunk.

Whether you hear it as a strange historical tale or a dark piece of inspiration, it makes for a memorable way to open an album called “Netherworlds”.

Recorded Apart, Brought Together in the Studio

The massive sound of “Netherworlds” might make you imagine the five musicians playing together in a room, feeding off each other energy.

That is not how the album came together.

The members recorded their parts separately, during different weeks, rather than jamming and recording together. Miiro Varjus, who had previously worked as the band live stage technician, took charge of putting the pieces together.

His role went beyond recording and production. He also directed the vocal arrangements, choosing whether Niilo Sevänen, Ville Friman or Markus Vanhala should sing each section.

Varjus also pushed the band into unfamiliar territory with fluid tempo changes inside individual songs. Insomnium have often relied on more fixed tempos, but here, sections speed up or slow down to change the mood and pull listeners deeper into the music.

Sometimes, a small change in pace can make a heavy passage feel even more intense. On “Netherworlds” that becomes part of the album emotional language.

Real Losses Behind the Dark Lyrics

The darkness on “Netherworlds” is not just about atmosphere.

The album explores nightmares, dreams, life and death, with its lyrics shaped in part by the loss of close friends and relatives experienced by Niilo Sevänen and Markus Vanhala before the writing sessions.

That personal weight comes into focus on the closing track “Journey’s End”.

The song imagines a peaceful, almost otherworldly inn where the dead gather before moving completely into the netherworld. After an album filled with gloom and heavy emotions, the idea offers something different: a quiet place beyond the pain.

It is a fitting concept for a band that has always known how to find beauty inside sadness.

Amorphinsomnium: When Insomnium Meet Amorphis

One of the album biggest surprises arrives with “The Hour Grows Late”.

For this epic track, Insomnium brought in three members of Amorphis: Tomi Joutsen, Tomi Koivusaari and Santeri Kallio.

Their contributions include guest growls, clean vocals and vintage 1970s sci-fi synthesizers, giving the song a different character from the rest of the record.

The result has even inspired the joking nickname “Amorphinsomnium”.

With members of two major Finnish metal bands sharing the same track, this is the kind of collaboration that should grab the attention of fans of both groups. The combination of different voices, heavy guitars and old-school synth sounds also makes it one of the album most unusual moments.

Ten Songs on the Standard Edition, Three More for the Deluxe Release

The band initially recorded 13 tracks for the album cycle. During the final stages, Jens Bogren helped narrow the standard edition down to ten songs, leaving three additional tracks for the deluxe artbook edition.

That means there is more “Netherworlds” to discover for listeners who want to explore beyond the main album.

And if the record leaves you wanting more of Insomnium dark world, those extra tracks could be worth tracking down.

Insomnium’s Netherworlds: A Strong Return to Form?

Early critical reactions have been positive, with the album reportedly averaging around 8.5/10 across major metal publications. Zware Metalen praised the value of recognisability, noting that “Netherworlds” delivers the sound listeners expect from the Finns while adding enough subtle changes to keep it fresh.

That balance is what makes this release interesting. Insomnium are not throwing away their identity to chase something new. They are taking the sound their fans know and giving it more room to move.

The lineup brings together Niilo Sevänen on harsh vocals and bass, Markus Vanhala on lead and rhythm guitars and clean vocals, Ville Friman on rhythm guitars and clean vocals, Tomy Laisto on lead and rhythm guitars and Markus Hirvonen on drums.

Together, they create an album that connects the band melancholic roots with a more dynamic, progressive edge.

“Netherworlds” is out now through Century Media Records. If you are in the mood for melodic death metal that can hit hard while leaving you with something to think about long after the final note, this is one release to put on your listening list.
