The music recorded by Ernest Greene as Washed Out has been nothing if not dreamy, but for his second full-length, he’s taken the idea of letting your mind wander to another state a huge leap further. On Paracosm, due out August 13, the Georgia-based musician explores the album’s namesake phenomenon, where people create detailed imaginary worlds.

The concept has been used to describe fantasy lands like Tolkien’s Middle Earth and C.S. Lewis’ Narnia, and it’s at the heart of the 2004 documentary In The Realms Of The Unreal about outsider artist Henry Darger.

Small Black will be the opening act.
