Miasma & the Carousel of Headless HorsesThey sure have an interesting name, and an interesting amalgam of rock vibes and orchestral composition. Very relaxing, pretty good to put on if you're doing a million other things in no grand hurry.
UtopiloSupposedly one person is behind this. It sounds like Crystal Castles to me but with more energy.
UnisonVery atmospheric electronic with the occasional overly distorted guitar + some post processing. I find it relaxing also.
Cloak of AlteringI've always liked artists that experiment with genres, even haphazardly. There's lots of random ambient breaks and odd pattern transitions with some good old (new?) metal.
