I'm new here. Been lurking around for a while and I was not expecting to find Loscil as a top comment on this post, so I had to register. I love music, and I love Loscil. If anyone asks me for an ambient/chill out recommendation, Loscil is my go to. Matter of fact, I have Monument Builders in my playlist for tonight, for after I finish the latest Unobscured podcast.
Ever since Scott's first work came out he's been steadily releasing great ambient. He hasn't tried to change his formula, or innovate in such a way that his music becomes meaningless. He found his formula and is still sticking with it. Plume sounds just as good as Equivalents, and there is 13 years between those albums. Find another electronics artist you can say that about after first encountering them. Boards of Canada maybe, but they barely around. Also, no discredit to Tim Hecker, jic.
Just as you say, it is the perfect background music, whether you're chilling or trying to concentrate. Or music to fall asleep to instead of white noise, but then more interesting. Loscil just never disappoints. Even in sun overflown and humid Thailand. Although it is rainy season now.
