The world learned Bibi Bourelly's name as the mastermind behind Rihanna's "Bitch Better Have My Money." What you might not know is that the singer/songwriter also wrote RiRi's track "Higher" and has worked with the likes of Lil Wayne, Nick Brewer and Usher. Freshly turned 21, the Berlin-born singer takes her step today out of the studio shadows and into the light of the internet with her own debut single. 

Titled "Ego," the track is a brazenly bluesy track slowly churns out Bibi's guttural vocals that grind and scratch below the surface, unfurling like an emotional purge in the gut before that ear-clinching chorus comes around as she declares she "won't never ever, ever, ever, ever, ever, ever give a fuck." By the time the bridge hits, it's nearly impossible to turn a blind ear to the unabashed authenticity that seeps from the track's pores. It all makes for a tremendous debut effort that strikes like a defiant call-to-arms anthem that Bibi hopes will empower listeners “to have a little more backbone and be a bit louder.” Listen to the track out now on Def Jam Recordings above or stream it on Spotify and iTunes.
