Eluvium's immensely long Nightmare Ending is intended as a follow-up to Copia, the last of his ambient, landscape-y electronic albums; it came out in 2007. The cuts in Nightmare Ending apparently came the material that he gave up on in 2009 or so, because it was too similar to his previous output, and then went on to record the very different, vocally-centered Similes. (I liked this last album a lot and interviewed him about it for PopMatters.
Anyway, there are few vocals on this new album (which must be a double-disc? I got mine electronically, no indication of format, except that it's 84 minutes long), one of the most haunting and beautiful belonging to Ira Kaplan of Yo La Tengo in a song called "Happiness" streamable below.
