I still find it strange to be writing into the void like this, and I have no idea if anyone is reading, but . . .
The book exists as a material object in the world as of late March 2015. I don’t have my copies yet but knowing this is enough for me to post that the chapter-by-chapter listening guide will hopefully be available here by sometime in April (before the official publication date of May 1). It’s mostly drafted, and there will be loads of music for you to play as you read or to listen to independently (or both).
