Rapoon--What do you Suppose? (The Alien Question) 2CD reissue. The original album is in my top three Rapoon albums, so if you don't have it, definitely buy this. A 2nd disc of new mixes of original tapes and unreleased material from those sessions is here, and is simply awesome.
Aun--Fiat Lux. New on the Cyclic Law label, this is another great cosmic space ambient release on this dark ambient label. A lot of CL releases I ignore because they're of the noisy oppressive variety, but this disc is highly atmospheric, mostly serene and quite different in a good way from their first CL release. Lots of heavily treated guitars and synths. Actually a very beautiful album. This goes on my best of 2015 list so far.
Brian Eno--Neroli. Sleep music at its best.
