First of all Alfarmania & Proiekt Hat albums, especially "Mardrömd Dödsström". These projects complement each other perfectly, I enjoy listening to everything these guys have recorded together.
SS WOM is also a great collab. Listening to their only album really transports my mind to a graveyard of ships.
Recent releases of Zyklon SS & Xenophobic Ejaculation, namely "War's Wild Beast" and "Whites Only" are now regulars on my playlist. I was especially pleased with Pekka's active presence on "WWB", whose style can't be confused with anyone else. The album is very diverse, yet elaborate and heavy as panzer armor. I rarely listen to live releases, but "Whites Only" is exactly the case when a live recording sounds as interesting as a full-length album. The insane pressure of this performance is comparable for me to the "Live In Finland 2016" by ZSS. I was pleased by the presence of samples from Black State's "Hlose".
Pissoir Rouge & Scatmother sound great together. I really like "Toxic Masculinity" for its more diverse and thoughtful sound compared to the previous albums. Of course, I also like the piercing high-qreq. attacks on "Physics Dissolve In Urine" and "Hentai Femdom Aktionismus", these albums sound more spontaneous and raw and there is a great in that too. I'm glad that the guys are experimenting and producing varied material.
Sick Seed & Zyrtax have a fine web release "Crimson Glow", which I hope will be released on CD \ tape someday. I really like this minimalistic industrial with Pekka's signature psychedelia. It seems that here among other things they used some leftover samples from Sick Seed's "Failed Rituals", which I also love a lot.
