SINGAPORE - You know you have a clear winner when the Singapore Indoor Stadium is packed with more than 9,000 people in the audience, all laughing, dancing and singing along while waving light sticks and lit mobile phones. Of course, Katy Perry’s Prismatic World Tour had been making waves even before it reached our shores, since the tour began in the middle of last year. And apart from a highly publicised glitch — at the Superbowl show, one of her dancers, dressed as a shark, obviously forgot his moves and started free-styling — the tour has rolled across the world pretty smoothly. According to Pollstar, the tour was the fourth best-selling in the world last year and the best-selling by a solo female artiste, having earned a gross of US$153 million (S$203 million) at the end of last year. At the 2014 Billboard Touring Awards, the tour won the award for Top Package.

On Monday night, the unapologetically irreverent show-stopper brought the house down with another adrenaline-pumping concert. The multi-award winning solo artiste will wrap up the Asian leg of her tour later this week, and despite having done 140 shows thus far (not including showcases), it was clear that Perry could still showcase the talent and passion she’s famous for.

Opening with her boisterous hit single and fan favourite, Roar, the glamorous 30-year-old proved that she had no problems singing live and thrilled her adoring crowd of KatyCats — as her fans are called — with two-and-a-half hours of dynamic song and dance. All this on a stage filled with outrageous props (such as the larger-than-life diamond-studded mechanical golden horse she rode), costumes (some which would put Kim Kardashian to shame) and, yes, the creative play of lasers, flashy animation and effects using ultraviolet light to make the colours pop even more.

The show was split into different segments and true to her inimitable brand of quirkiness, Perry presented an unabashed wardrobe: Think sexy Egyptian queen-meets-sparkly Xena, Warrior Princess. As the show went on, she was decked out in various outfits, from a sci-fi-looking neon mini-dress complete with a luminous green wig to an adorable sunflower pixie frock with blinged-out guitar to a sophisticated evening gown with firework motifs (guess for which song?), but the most memorable costume was a furry pink leotard that looked like something she borrowed from Andrew Llyod Webber’s musical, Cats — albeit one that came with a dramatic splash of Josie And The Pussycats thrown in.

Looking around, the lively crowd was a good mix of excited tweens with their amused chaperones, as well as playful adults — many who had no qualms wearing flashing Katy Perry headbands that sparkled red and blue. It was all in good fun of course: Several hard-core fans even dressed up for the occasion, taking much inspiration from Perry’s kooky music videos. A middle-aged man came dressed as a hirsute pharaoh, as featured in the Dark Horse video; another came dressed as Perry’s infamous shark dancer; and a group of girls sported neon wigs in every colour of the rainbow.

Eighteen-year-old Bryan, whom Perry plucked from the front of the mosh pit to join her on stage, drew the envy of many fans. He was rewarded with hugs and a selfie moment with the sassy singer after she asked him to teach her some Singlish. Besides learning the colloquial exclamations — “lah”, “leh”, “lor”, “hor” and “meh” — Perry also gamely picked up some Mandarin (“xie xie”) and Hokkien (“kam sia”) from her shy Singaporean fan.

It wasn’t only hyper-activity on stage: About three-quarters of the way in, she brought out numbers done acoustic-style, such as By The Grace Of God and Unconditionally. And then it was back to the beats. Before the performance ended, the audience was treated to the hilarious sight of six giant bobbing balloons — one of which featured what looked like a humongous swirl of brown poo — as well as a generous shower of confetti before a shimmering display of “fireworks” that could be seen with the free kaleidoscopic glasses ushers had handed out earlier.

The hardworking entertainer revealed that this concert in Singapore marked her 140th show and thanked everyone for making it possible, especially those who had travelled hours just to see it. It seems like Perry certainly knows how to up her game with every tour.
