He and his drummer brother Mario say that many of the album's songs were half-written when their mother died.

Joe tells Rolling Stone: "The songs were half-written while she was sick. After she died, I still had to finish them. So one song was like, 'You're going to make it,' but the second verse is 'You didn't make it.'

"I felt physically, mentally exhausted. At the same time, though, the way it happened was beautiful. We were all around her. We had to cancel a few shows when she died, but it was very enriching at the same time. We learned a lot about death."
