Katy Perry has recently unveiled details of her new concert tour “Witness,” Billboard reported. Her newest tour is kicking off on September 19 with the first show happening in Montreal.

The singer told Billboard that “Witness” is a more mature version of her previous concerts “Prismatic World Tour” and “The California Dreams Tour.” She added that it will feature “moments of playfulness and light-heartedness.”

Furthermore, she is also set to introduce new features that have never been shown before. In line with her newly-released single “Swish Swish,” Perry revealed that the song will be performed through an “interactive game with the audience.” The song’s music video featured the singer as a basketball player while defeating her celebrity opponents in a match.

Perry will also be unveiling her “huge, angelic” wings as she performs the song “Power,” Billboard reported. She described her upcoming “Witness” concert tour as an evolutionary take-off from her previous shows. However, this tour will focus on cities located in the Western part of the world, unlike her previous performances that brought her to various Asian destinations.

Begins in Montreal

The North American leg of the “Witness” will happen in the areas of Montreal, Quebec, Vancouver and Toronto, Radio.com reported. After the first show on September 19, she will head to several United States cities such as Pittsburgh in Pennsylvania, Columbus in Ohio and Boston in Massachusetts.

She is also set to visit Washington, D.C., New York, Louisville, Nashville, Salt Lake City, Chicago, San Jose, Los Angeles, Des Moines, Miami and Orlando among many other cities in the United States.

Her shows will generally involve the audience through “making eye contact and touching hands,” Perry said.

The final leg will be held at the Rogers Arena in Vancouver, British Columbia on February 5, Radio.com added.

Conflicting schedule

Katy Perry’s next projects might go in conflict with the taping of the upcoming “American Idol” auditions, according to entertainment news source TMZ.

The singer will soon begin her concert tour which will kick off in Montreal on September 19.

“American Idol” has previously chosen Perry as one of the judges for their new season. But unforeseen circumstances concerning the schedule of the celebrity judges might delay the shoot of its first episodes.

The reality singing competition will have the final leg of its bus auditions within a few days, the entertainment gossip website revealed. The production team is also set to begin the taping of subsequent episodes featuring all the judges watching the hopefuls audition.
