Katy Perry roars on resplendent rabble-rouser "Rise"

It's in the vein of "Roar" - a big, chest-pounding anthem full of self-belief and warrior-like strength. A pretty good choice for the NBC's Rio 2016 Olympics theme, then.

“This is a song that’s been brewing inside me for years, that has finally come to the surface. I was inspired to finish it now, rather than save it for my next album, because now more than ever, there is a need for our world to unite,” says Perry. “I know that together we can rise above the fear - in our country, and around the world. I can’t think of a better example than the Olympic athletes, as they gather in Rio with their strength and fearlessness, to remind us how we ALL can come together, with the resolve to be the best we can be. I hope this song can inspire us to heal, unite, and rise together. I am honoured that NBC Olympics has chosen to use it as an anthem before and during the Rio Games.”

Perry's latest record, Prism, was released in 2013.
