In "Rocks", Perry reveals that he considers Steven Tyler family, despite the fights the two have had through the years. "He's the brother I never had, which is a lot of the basis for our dynamics," Perry tells Billboard.

"[The other band members] play an important part in mediating. Though when push comes to shove, when the two of us are in a room and it gets down to the real nitty-gritty, we have to deal with it ourselves. That's what makes it exciting."
