Katy Perry isn’t one for subtlety — and her current world tour is definitely more psychedelic than sedate.
If you haven’t witnessed the visually vibrant songstress live, you can grab an eye-popping peek when EPIX debuts the concert film “Katy Perry: The Prismatic World Tour” Saturday at 8 p.m.
In November 2013, the singer told MTV that her then-upcoming tour would be a “feast for your eyes.” Tour director Baz Halpin says that’s an understatement.
“I think it’s an assault on your eyes,” he tells The Post, laughing. “This show is a monster — I’ve never designed a more technically ambitious show.”
The two-hour spectacle of LEDs, lasers, video and pyrotechnics was filmed on the tour’s stop in Sydney, Australia last year.
The stage features a massive 155-foot-long triangular catwalk — that’s four feet longer than the Statue of Liberty from base to torch — and a 78-by-36-foot video screen shaped like a pyramid.
Still, Halpin wasn’t worried about overshadowing the 5-foot-8 Perry, whose many costume changes reflect ancient Egyptian glam, cat iconography and her candy-colored “California Gurls” persona.
“You can go really big visually and it doesn’t overpower her because she is, on stage, a larger-than-life character,” he says of the 30-year-old singer.
Halpin — who also pulled together Perry’s heralded Super Bowl halftime show in February — shares his thoughts on the most energetic, complicated and treacherous songs on the tour’s set list.
Perry goes horseback riding — sort of — for “Dark Horse”
“Two guys carrying the weight of this horse puppet and then having Katy sitting on top of it — it’s heavy. In rehearsals, I remember them with the puppet choreographer, watching videos on YouTube of horses moving because it wasn’t just enough that they support the weight, move around the stage and hit their marks. They also had to look and move like a horse. I tried it — I got in the horse and tried to swing the legs. It’s really, really difficult.”
Gonna make her sweat
“‘Part of Me’ is a very energetic cardio workout. We have 50-foot-long treadmills running at full speed down either side of the truss, and she’s running and singing the chorus.
She’s already given it her all, and then she’s running in position, getting nowhere on this treadmill. It was exhausting. She had to institute more running and cardio just to be able to do that.”
Perry serenades a fan on stage
“She said, ‘In “Birthday,” we’ll have a birthday cake, a birthday chair and balloons and I want to bring up someone whose birthday it is.’ That’s 100 percent her idea. If she could bring everybody up on stage, she would. When we did the ‘California Dreams’ tour, she did [Whitney Houston’s] ‘I Wanna Dance With Somebody’ and brought 50 or 60 people on stage for a dance party.”
Soaring to great heights for “E.T.”
“We have this aerial where Katy’s sort of abducted by a flying pyramid. She lays on her back, and it was tricky finding a support board she could be hung from that was comfortable, wasn’t going to have wires digging into her skin and would also be minimalist so we didn’t really see it. We ended up making a mold of her back. We did a 3D laser scan of her back and made a clear plastic back board that she was levitated on.”
In “Hot and Cold,” Perry hopes she doesn’t need nine lives
“Everybody’s dressed in cat suits and she shows up on top of this giant ball of yarn with knitting needles in it. She’s got to do a ‘trust fall’ off the ball and be caught by the cats. That I think is probably the scariest thing for her because she’s got her back to the people catching her. It’s a trust fall, you know? The proof’s in the title.”
