Listened.
My favorite of them is They Go Long from Stalker. Very ambient. I can't help but compare it with Robert Rich and B.Lustmord's Stalker, a tribute composition saluting Tarkovsky's film. Both are creepy and atmospheric.

 

Fan of Tarkovsky's films, think that Artimiev's music is an integral part (Stalker may well be my all time favourite film). Have heard a few Artimiev works outside of the Film Music but (EAM and Vocal), but never felt that they had any real lift without the visual component!

The Ans Synthetizer was (is!) such an incredible instrument, and in my view it represented a revolution as those made by Schoenberg or Varese/Russolo.
I have some Artemiev's tracks on a album that collects experiments with the Ans made by various composers, Schnittke, Gubaidulina, Artemiev, Oleg Buloshkin, Denisov. Alien music that sounds truly ahead of its time. I agree with that comparison with that album of Lustmord and Rich, it reminds a lot of that kind of dark ambient.

 

he also wrote the music for a movie A Train Crashed (1982 Mosfilm)

 

As an aside, it's worth remarking how many tributes there have been to Tarkovsky from major classical composers--Nono, Takemitsu, etc. The following brief essay talks about how Tarkovsky's soundtracks and their influence:

*p.s.* Missed Norman Bates' post, which covers the same ground.

 

Some of the most expressive synthesized music I've ever heard. Very evocative. A real master at his art.
