In a June 2012 interview with HipHopDX, Ab-Soul publicly spoke on Joh's death and how it impacted him and the album: "I was actually pretty much done with the project before that happened. Luckily for me and all of us cause I definitely don't think I would have been able to put it out in the time that I did. It was difficult. It's still very difficult. She helps me out with all of my projects. It's a very difficult thing to get over but at the same time this is what we've been – we, me and her, were working on for the majority of the time I've known her. She was one of my biggest supporters so I feel like I owe her and I owe everybody else that's taken a liking to what we're doing." "The Book of Soul" was of the last tracks that he recorded on the project, he touches on a couple topics throughout his life, with Alori Joh being the main subject over a jazzy instrumental produced by Tommy Black.^[13]
