Part 1

Debut: SUNDAY, JULY 9 (9:00-10:00 p.m. ET/PT)

Years before they brokered one of the biggest deals in music history - the 2015 sale of Beats Electronics to Apple for $3 billion - Dr. Dre and Jimmy Iovine navigated very different environments towards destinies that would, ultimately and improbably, bring them together.

Dre's story began in Compton, Cal., where his fascination with dance music, DJ innovations and sound brought him into contact with Eazy-E, Ice Cube, DJ Yella and MC Ren. Together, they would become the core of the 1980s gangsta-rap supergroup N.W.A.

A native of Red Hook, Brooklyn, Jimmy gravitated to music following an indifferent academic career, and with a determination to avoid continuing in the family business as a longshoreman, he turned stints answering phones in recording studios to connecting with artists like John Lennon, Patti Smith and Bruce Springsteen through a combination of hard work and old-fashioned luck, eventually building a reputation as a fearless, talented and indefatigable producer.
