Dødheimsgard had offered up industrialised black metal on 666 International, went dark for a good number of years, and then re-emerged offering blackened industrial metal on Supervillain Outcast. Now, after another long break, the project has offered up A Umbra Omega, which sees Vicotnik and his new lineup taking Dødheimsgard back out of the industrial realm altogether to produce an album which retains a black metal foundation but gets extremely weird with it. With proggy synthesisers, jazzy brass sections, and a vocal performance from Aldrahn with a theatrical, eccentric delivery that puts me in mind of the sort of thing Devil Doll get up to, A Umbra Omega represents an avant-black puzzlebox which will reward patient listeners.
