Do you know Laibach

You are welcome!

Personally I did not listen very much of their work, especially early staff is quite industrial noise.

Artistic only? Yes and no! Because evrything is connected, they acted very politically in reality thru art form. They made mockery of post-titoist communist regime in ex YU, at the same time creating a virtual state, independent artistic "state" called Neue Slovenische Kunst (New Slovene Art), they even designed and issued NSK passports representing NSK "citizens".

They processed influences of Germanic/Wagnerian operetic art, political ideology of totalitarinism, industrial post-punk (Einsturzende Neubauten), theatrics on stage and phenomenology of pop music (they made covers/remakes of Beatles, Stones, Queen, Status Quo...)

They are from Slovenia and that country was a part of Socialist Yugoslavia before 1991.
They used multimedia artistic approach to make quasi-political statements about totalitarian regimes in general, be it nazi or stalinism.
They claimed that politics was a definite form of the art.
They used nazi-like uniforms combined with Slovenian alpine imagery and symbols of Russian futurist painter, Kazymir Malyevich's Cross as their logo.
They were quite radical/anarchist in terms of art (not politics) during the 1980s and were frequently attacked by regime socialist media in ex Yugoslavia.
The name Laibach is germanic name for Slovenian capital Ljubljana, which was called by that name during Nazi occupation WW2.
Apart from Opus Dei, probably their best (at least easy to listen) is their Let It Be album, entire cover of the Beatles album. Could be interesting for progsters....

I don't really get into the political aspect, but I've liked some of their stuff. "Opus Dei" is a favorite, though my wife always says it sounds like the Cookie Monster is doing vocals.
