Barto: "We had great respect for Bun B as an artist before we worked with him. He had gotten in contact with us and expressed that he wanted to work with us and we were like, 'Of course.' I didn't really know what to expect but artistically I had high hopes. When we finally got into the studio, from the first second after everyone was introduced, it was like, 'Let's get to work.' There was no bullshit. No talking back and forth. No joking around. It was just straight up, 'Let me hear some beats.' The first session we actually made a beat for Bun right on the spot. And he was writing the record while we were working on the beat. And he went ahead and cut that record then boom, on to the next track. We played him a few more beats, he picked one he liked, then went ahead and wrote a rap for that one. It was like three or four the first day.

"From then on, every time Bun was in town he would hit us up and book sessions. It was nothing but work the whole time. We were working with Bun heavy. All night sessions, seven in the morning and not leaving until seven. We were straight up picking beats, making beats, and recording records. We must've done ten records with Bun and 'Trillionaire' just happened to be one of them. But the whole experience was really humbling working with Bun B because he's legendary. The man does not play when it comes to work. If there was an artist boot camp he would be the drill sergeant.
