Janelle MonáeDiddy recently announced a new addition to his Bad Boy Records roster — in the form of singer Janelle Monáe.

Via a deal with Monáe’s Atlanta-based label, Wondaland Arts Society, the singer — who is said to be a mix of R&B, funk, and rock ‘n roll — will release an introductory EP titled Metropolis Suite in June.

Metropolis is the place I’ve been dreaming about all these years — a city inside your head,” said Janelle. “It’s an adventure the music brings to life.” Her full-length debut album will follow in September.

“Janelle Monáe is one of the most important signings of my career,” said Diddy. “Over the years, I’ve been blessed to work with some of the most influential artists in modern music — from Jodeci to Mary J. to Biggie — and there is no doubt in my mind that Janelle is the kind of artist that changes the game. She is a true visionary, with an original sound and a mesmerizing presence. I can’t wait to watch the future unfold for Janelle.”

In addition to Diddy’s faith in the singer, other artists also believe, including Outkast’s Big Boi, who’s a partner in the deal and calls her “one of most inspiring performers ever.”

“What I love about Janelle is that she has a magical ability to bring folks together,” stated Big Boi. “And she’s one of most inspiring performers ever. I’m proud to be partnering with Puff and the Wondaland Arts Society to introduce her to the world.”

Born in Kansas City, Kansas, Janelle Monáe moved to New York City after high school to attend The American Musical and Dramatic Academy, the prestigious music and theatre conservatory. Deciding to extend her range beyond classical and Broadway, she moved to Atlanta to explore the possibility of becoming a recording artist. Upon arrival, she garnered a huge cult following by performing for college students at the Atlanta University Center (AUC). It was during one of these performances where Monáe met Nate “Rocket” Wonder and Chuck Lightning of Wondaland Productions and began work on the concept and music that would form “Metropolis.”

While working on her own music, Janelle collaborated with Big Boi on the tracks “Call The Law” and “In Your Dreams” on OutKast’s “Idlewild” soundtrack. It was through Big Boi that Monáe came to the attention of Sean Combs, leading to her new pact with Bad Boy.
