Voidhanger have put up live footage of Dyskretny Urok Upadku, filmed in Poland this year.
There is no album behind it and no date attached, which for this band is normal. They came out of Katowice in 2010 playing the version of black metal that keeps the thrash in it, closer to Aura Noir than to anything symphonic, and they have released at roughly the pace of a band who all have other jobs.
Agonia Records have carried them for most of that. Three full lengths sit in the catalogue, the last of them built out of short songs with the bass audible, which is the detail that separates them from most of what Poland exports under the same label.
Live is where that arrangement makes sense. The recording is a single song rather than a set, taken from a room small enough that the audience is part of the mix, and it is the first thing the band have shown publicly in a while. Whether it is a trailer for something or just a night they liked, nobody has said.
