The countdown is on as the 2016 Rio Olympics starts next month on August 5. As a part of Gillette’s “Perfect Isn’t Pretty” campaign, producer Ariel Rechtshaid provides a remix of Sia’s “Unstoppable” anthem that features a guest verse from G.O.O.D. Music’s Pusha T. The “(Perfect Isn’t Pretty Mix)” also includes percussion from Afro-Brazilian marching band Olodum.

Sia, who’s a friend of mine, and then Pusha T came in towards the end because the song felt like it could use his edge and a verse on it,” Rechtshaid tells Billboard, who premiered the song. “People get to see the end results a lot and they think it was a beautiful ride,” says Pusha in a mini-doc that also comes with the song. “They don’t even think about the steps it took to get to that final place.”

Listen to the remix and watch the mini-doc below.
