In a forthcoming interview with Blunt Magazine to be published in September, Rudess says he contributed to a number of sessions on a variety of vintage and otherwise interesting keyboards.

"One day I walked in and there were two pianos, a baby grand and a really funky upright," Rudess says. "I thought "Okay, I'll definitely be playing the baby grand." But no, David's piano was this funky upright and he was having it especially tuned for this album. Then producer Tony Visconti said "Y'know what? Don't play the upright, play the baby grand but we'll mic the upright which is right next to it, we'll tape the sustain pedal down on the floor and we'll mic the resonance of the upright piano."
