I went on my own and kind of like just figured out a whole new life, which was really dope, but the experience there taught me a lot about music, too. I would say that I never really stopped [making music], but the actual itch to do this project right now was when the music felt right. And then from there, I felt like it was personally my shit. Like if I have a conversation with somebody and they say something profound, I'll write it down. It has to be somewhere between [Andre 3000's] .
