Chained to the Rhythm hitmaker Katy Perry has collaborated with global media and technology company Comcast's Xfinity brand to launch a new on-demand service, Xfinity X1, allowing fans to see behind-the-scenes tour footage and content from the singer's upcoming Witness tour.

Perry commented 'I’m excited to team up with Xfinity to share the whole Witness experience with my fans. It means a lot to me for all of my fans, no matter what their situation, to feel like they can come along for the ride.... It’s a real peek behind the curtain, and up close and personal access to me throughout the tour'.
