First of all I chose the names above because I think are very productive, some of them overproductive, and have many years in the scene (except from Vir Unis but he has collaborated with many of the guys above and follows a similar style)..
At first I thought of writing some stuff about each producer and recommended their albums, but what to recommend? I recommend almost EvERYTHING and ANYTHING by them , especially Biosphere, Steve Roach, Robert Rich, Vidna Obmana , Vir Unis...
Vidna Obmana (Dirk Serries) http://www.discogs.com/artist/Vidna+Obmana
My favourite one.."Vidna Obmana" stands for "optical illusion" in serbian language.
I find most of his ambient to be really entrancing, I especially like the albums where he uses a lot of tribal elements. Vidna Obmana plays percussions and digeridoo and these are quite dinstict in a lot of his creations.
His most 'normal' ambient such as THE RIVER OF APPEARNCE can be quite emotional
