Billboard:

The new album is called “4.” Aside from this being your fourth solo album, what significance does that number hold?

We all have special numbers in our lives, and 4 is that for me. It’s the day I was born. My mother’s birthday, and a lot of my friends’ birthdays, are on the fourth; April 4 is my wedding date.

How did the creative process begin with the new body of work?

I recorded more than 60 songs: everything I ever wanted to try, I just did it. I started off being inspired by [Afrobeat music pioneer] Fela Kuti. I actually worked with the band from “Fela!” [the hit Broadway musical based on his life] for a couple of days, just to get the feel for the soul and heart of his music; it’s so sexy, and has a great groove you get lost in. I loved his drums, all the horns, how everything was on the one. What I learned most from Fela was artistic freedom: he just felt the spirit. I also found a lot of inspiration in ’90s R&B, Earth, Wind & Fire, DeBarge, Lionel Richie, Teena Marie… I listened to a lot of Jackson 5 and New Edition, but also Adele, Florence + the Machine, and Prince. Add in my hip-hop influences, and you can hear how broad it is. I also gave myself more freedom to really belt out some songs, and bring soul singing back: I used a lot of the brassiness and grittiness in my voice that people hear in my live performances, but not necessarily on my records.
