On Saturday afternoon, a bride and groom walked hand in hand up the steps of Los Angeles City Hall. She wore a yellow lacy dress and veil, he sported a white tuxedo and bowtie, and they disappeared inside the building together, giggling. A few onlookers stared inquisitively, and several teenagers on skateboards turned to a group of us gathered on the sidewalk and asked: "Hey, what movie is this for?"

Though the couple were indeed actors, they weren't in a movie. Their City Hall nuptials were part of a mobile opera called Hopscotch that is zig-zagging through Los Angeles' bustling streets in 24 cars for a month-long run.

Hopscotch aims to bring a genre long associated with older audiences to new generations, and to a new, unexpected setting — city traffic.

Hailed as the world’s first opera to take place on the road, the 90-minute experience begins at a secret departure point disclosed to attendees only days before the performance. In my case, it was a warehouse near the Los Angeles River, and from there, I was ushered along with three other attendees into the first of eight limos we would be clambering in and out of that afternoon for stops at city landmarks.

Our journey was the Yellow Route, which included eight of the opera's 36 chapters, unfolding in 10-minute scenes arranged in an entirely random order. The narrative's chronology is intentionally murky, but the entire story tells of of a decades-long love triangle between Jameson, Orlando and Lucha — a beautiful heroine embodied by different actresses but always distinguished by a pop of yellow.

As the scenes played out, I saw Lucha and Jameson on their wedding day, Lucha heartbroken over Jameson's infidelity and much later in life, old friends Lucha and Orlando reunited and in love. In between, there were dancers rehearsing, a scientist experimenting and a silent man playing music on champagne glasses. Told only in snippets, the finer points of the plot are intentionally difficult to follow, but the overall story tells of love, loss and a longing for what once was.

Though most of Hopscotch's dozens of singers, actors and dancers don't interact with the audience, they're not kept at a distance — some asked questions of or even touched audience members. The confines of a limousine certainly made for the most intimate opera performance I'd ever experienced. Each scene is scored by one of six different Los Angeles-based composers, and outside, some singers zipped by on motorcycles as special tech in their helmets piped their voices inside. Trumpeters stationed along the streets provided musical accompaniment perfectly timed with each scene.

Hopscotch’s three routes — Red, Yellow and Green — run three times a day each weekend, spotlighting eight different chapters in no particular order, with each new audience beginning with a different chapter.

Sometimes operas don't use amplification. Sometimes they rig up motorcycle helmets so singers can ride while serenading the audience driving in a limo alongside.

Hopscotch makes stunning use of downtown Los Angeles, too, from its crumbling art deco theaters to the Bradbury Building, made famous by films including Blade Runner and 500 Days of Summer. Even city walls are given star treatment: A projector rigged atop one limo creates otherworldly animation sequences inside downtown's gritty tunnels. That drew several gasps from my group.

Many have argued that LA has long played a supporting role in the film and television it has created, serving only as a backdrop rather than a main character, and Hopscotch has countered this by giving Los Angeles a starring role.

Throughout the performances, each of the opera's 36 chapters is live streamed back to Hopscotch’s main hub at the Southern California Institute of Architecture, and for scenes that take place outside of the limousines, one audience member per group is provided with a cellphone to film the action themselves.

Hopscotch is produced by experimental opera company The Industry, and is the brainchild of founder and director Yuval Sharon and production designer Jason H. Thompson. Sharon’s last project, Invisible Cities, was also a mobile opera experience that incorporated another of downtown’s iconic structures, Union Station.

“The way that most of us really experience Los Angeles is by driving through it and listening to our own music on the radio and living in our own kind of private world,” Sharon said. “I thought, wouldn’t it be amazing if we could use music to really transform our view of the city and also the reality of the city around us.”

Hopscotch is certainly a modern operatic experience — guests arrived in jeans and tennis shoes, and it is an active experience, to say the least — there's no chance of dozing off in your seat during this performance.

"For me, what makes this so special is the immersive and interactive aspects of it," said Ashley Leonard, who purchased Hopscotch tickets for her boyfriend Anthony Lioi's birthday. "You're not just a spectator sitting there minding your own business. You're involved and you're encouraged to participate to an extent. We're drawn to things like that."

The couple said they were already fans of interactive performances and had been looking forward to Hopscotch after hearing about Invisible Cities last year, but said the mobile opera still managed to exceed their expectations.

"Hearing the trumpet in time with the music that was being played and sung and performed inside the car, and then all of a sudden it transcends the little space that we're in and it's out on the street, it was perfectly surreal," Lioi said.

For those unable to snag a ticket or visit the main hub, you can watch animated videos of the opera, which runs through Nov. 22, online, some of which are included below.
