In 2013, Mr. Rodgers teamed up with Daft Punk and Pharrell Williams for the ditty “Get Lucky,” which has sold 9.3 million copies and won him three Grammy Awards, including Record of the Year. And since that time, he has been on a victory tour rare in the youth-driven music business.

Admittedly, some things have changed about Mr. Rodgers since his heyday.

The flattop is gone, replaced by the dreadlocks he wears underneath a backward Kangol hat or navy bandanna. So is the “Miami Vice”-inspired 28-foot cigarette speedboat.

The white powder that was once his main dietary staple has been swapped for stevia, packets of which were strewn all around the house — on top of his alligator-skin side table in his living room, on his desk in the upstairs recording studio and in his bedroom, where he packed for a gig Chic was due to play in Milan, opening for Duran Duran at the Piazza del Duomo.

On the bedside shelf was a picture of Mr. Rodgers’s mother, Beverly Goodman, and a copy of his memoir, “Le Freak: An Upside Down Story of Family, Disco and Destiny,” which was published in 2011.

The CliffsNotes version goes something like this.

Ms. Goodman was 14 years old when she gave birth to Nile in New York City. He met his own father, a traveling musician named Nile Rodgers Sr., just a handful of times.

Sometime around his second birthday, Ms. Goodman met Bobby Glanzrock, who became his stepfather and introduced his mother to both heroin and to Richard Pryor and Lenny Bruce, who spent a lot of time at the family pad.
