Astoreth & Forestaal deliver a nearly forty-minute improvisation, a musical ritual built from drones and vocals.
Stepping outside the usual genre boundaries, this week I’m also highlighting a Swedish neoclassical-darkwave band, Arcana. Their 2012 album “As Bright As A Thousand Suns”, originally released on Cyclic Law, is now available again on CD and vinyl.
Kloob and Onasander’s previous collaboration was already featured in an earlier recommendation, and now they return with a new joint project: Ethnea Nekrōn. Their release Exo-Metempsychosis explores the theme of cosmic rebirth through dark and space ambient textures.
From Helsinki comes Ruusuriimu (Csipkebogyó), offering transcendental apocalyptic folk with a touch of Hungarian connection. Their new album, “Tánc a rothadásért”, features Hungarian vocalists Vály Tekla and Csiszér Réka. Tekla also contributes lyrics and the cover photograph.
First up is the debut album from Kristof Bathory (Dawn of Ashes) and his new dark ambient side project, Bleak Haven. Oblivion dives into dark space ambient territory with subtle hints of horror.
Insectarium sets a similarly moody tone with their latest release, Replicant. This one leans toward sci-fi, featuring colder soundscapes and layered drones.
The same artist also released another album back in August, but due to the summer break, Witness This Strange World Unfold is only coming to light now.
Finally, there’s a new Kult of O mixtape, featuring Void Gazer, Steve Roach, and many more artists.
In the first Unearthed after the summer break, we’re tuning in to the collaboration between Kloob and Onasander on their album Goês. Its slow, pulsing drones conjure the spirit of the dead in the final chapter of the Witchcraft trilogy.
Sonologyst’s album Planetarium is a musical disovery of the Solar System using recordings from NASA. It’s cosmic ambient in the truest sense of the word.
Finally, we have another space/dark ambient release from Joel Gilardini, who makes experimental sound textures from guitar recordings to create slow, immersive tracks.
Two weeks’ worth of recommendations are coming out together this time — I’ve slowed down a bit; it’s summer, it’s hot, that’s how it is. In return, I tried to gather enough so that you’ll have something to listen to for an entire vacation.
To start, here’s Oneirich’s new mixtape — less ambient, more pulsing, travel-like rhythmic tracks:
Let’s not forget the usual Nacht either — the July 27 mixtape:
I already recommended Ajna last time, now here’s a new release from them (under another name, as Segment.fault).
Caldon Glover’s Eternal Night Radio album also came out recently — I unfairly forgot about it, but I’m making up for that now.
Also a new release: a compilation inspired by the film Eraserhead, featuring tracks by Grey Frequency and Sonologyst, among others.
And since I mentioned Sonologyst, here’s one of his older albums from 2015 — Ancient Death Cults and Beliefs.
Something special from 2020: a recording of a performance without an audience, a collaboration between Inade and Circular — The Saturnine Broadcasting.
And let’s close with Oneirich again, who recently put together an industrial mixtape as well.
That’s all for this round of recommendations, I wish everyone a great summer holiday! I’ve added all I could. Since I’ll be going on vacation soon too, expect new posts in the last week of August.

To finally have something industrial-themed: on March 1, 2026, KMFDM will be at A38!
In Depths Forgotten by Insectarium – slow soundscapes, huge spaces and underground meditations define Joel Hinkle’s new album.
