Witness: The Tour was the fourth concert tour by American singer Katy Perry, in support of her fifth studio album, Witness (2017). The tour began on September 19, 2017, in Montreal, Canada, and concluded on August 21, 2018, in Auckland, New Zealand. Perry visited North America, South America, Asia, Europe, Africa and Oceania.

In February 2018, Katy Perry announced via Twitter that she would record her two shows in Vancouver for a special project. It has been a year and a half and we still do not know what that project was about. 

We want to use this platform to let Katy Perry and her team know that her fans are here for another live movie and If possible, her second live album. Most of her fans around the world could not live the experience of WTT, but this could be a great opportunity for them to enjoy Perry´s performance. Her KatyCats also think that a Netflix Original or an Amazon Prime Video Original could be a great idea for them to dive into this experience.
