Though we know Mariah Carey as a high-maintenance diva, there's a LOT more to the story. She grew up in an incredibly turbulent environment with a family that could have very easily kept Mariah down (and keeps trying to). Her professional and personal life also merged in her early 20s, when she married a music exec who treated her like a prisoner. We'll get into Mariah's desire to shift "Daydream" to a more R&B sound, her signature whistle tones, and the earliest years of her global success. Episode 1 of 2.
