I thought I'd take a moment to mention Passage, a netlabel out of Russia. It's actually "an ambient sub-division" of their more techno-related label Fragment, which has been on the rather quiet side and without a release since late 2007.
However Passage have been consistently active since it's inception in 2009, making up for the now defunct ambient side of Thinner: Autoplate (though the archive link is now currently inactive??).
But Passage really makes up for it. The releases are exquisite, currently tallying up to a total of 5 - including the likes of Feldmaus, Clouds In My Home, Doyeq and Gaston Arovalo - the latter of which is a particular favourite of mine.
The latest release - 'Strange Dreams' by Slow (http://www.sergeysuokas.ru)- is an artist which I know little about, but who nevertheless provides a beautiful dreamy full length, which is surely one the labels best.
As Suokas describes: "I willed to make this album sounding a bit lo-fi dried – a little hues from the past, world of dreams and unexplored lands, a little femininity and tenderness, simple and somewhat psychedelic melodies, all in all just for a pleasure listening”.
All in all Passage is a beautiful label, it's quite rare to find such high quality releases that provide the good without even charge a dime. I really look forward to future releases.
Be sure to check it out
