The North American leg of WITNESS: The Tour produced by AEG Presents will make a stop in Detroit at Little Caesars Arena on Wednesday, December 6 at 7 p.m. with opening act Purity Ring. All U.S. concerts on WITNESS: The Tour are presented by Xfinity. Additional sponsors are Citi, COVERGIRL and KATY PERRY PARFUMS.

WITNESS: The Tour follows Katy’s sold-out, 151-date Prismatic World Tour, which concluded in 2015 and was hailed by Rolling Stone as "a show to damage retinas and blow minds."

Katy made her Capitol Records debut with 2008’s One of the Boys after signing to the label in 2007. She cemented her status as a global superstar with the follow-up album, Teenage Dream (2010). PRISM, her 2013 album, debuted at No. 1 on iTunes in 100 countries and has sold more than 12.5 million adjusted albums worldwide. With the singles “Firework” and “Dark Horse” each surpassing the 10 million threshold including song sales and streams, Katy is the first female artist to earn two RIAA Digital Single Diamond Awards. In her 10 years with Capitol, she has racked up a cumulative 18+ billion streams alongside worldwide sales of more than 40+ million adjusted albums and 125+ million tracks. She is the most-followed person globally on Twitter.
