Years and years ago, I read a great interview with Jam and Lewis, the R&B producers, in which they described what it was like to be members of Prince's band. They'd sit down, and Prince would tell them what he wanted them to play, and they'd explain that they couldn't--they weren't quick enough, or good enough. And Prince would push them and push them until they mastered it, and then just when they were feeling pleased with themselves for accomplishing something they didn't know they had the capacity for, he'd tell them the dance steps he needed to accompany the music. This story has stuck with me, I think, because it seems like an encapsulation of the very best and most exciting kind of creative process.
