la-la land

Here’s to the ones who dream.

The anthemic thesis of “La La Land” — the Ryan Gosling/Emma Stone movie musical celebrating its 10th anniversary — became a moment of musical reality in May when a 21-year-old student in Sydney, Australia, was plucked from the crowd at a live concert of the film during intermission. Sterling Nasa proceeded to stun composer-conductor Justin Hurwitz and the 2,000-person audience with his flawless, impromptu performance.

“Jumping into that concert in Sydney, and having an earpiece and seeing all this, was a little bit crazy,” says Nasa with well-mannered modesty, “but we somehow got through it.”

Nasa is sitting backstage at the Greek Theatre between rehearsals, preparing to make his Los Angeles debut. After that remarkable incident, an international feel-good news story, Hurwitz invited Nasa to fly out and play the entire concert at the anniversary screening here, in Griffith Park, where many of the film’s iconic scenes were shot.

“He’s playing better than most of the professional pianists I’ve worked with,” says Hurwitz, who regularly conducts “La La Land in Concert.”

“He’s nailing it,” Hurwitz explains during a break. “Those Sebastian solos, the ones that Ryan Gosling plays in the movie, he’s playing those as perfectly and cleanly as I’ve heard them in a very long time. Very few of the pianists I work with around the world — and they’re all great professionals — but very few of them play it this well in sync with the picture.”

Saturday’s rehearsals took place under a scorching sun. Half of the assembled musicians played on the film’s original soundtrack; star trumpet soloist Bijon Watson can even be seen wailing in the Lighthouse jazz scenes. Sitting in the midst of these veteran L.A. sessions players, Nasa looked focused but confident, his youthful face belying his easy, fleet-fingered playing.

He flew in from Sydney on Thursday, leaving a rainy Australian winter for a California heat wave. The initial jet leg was rough, he says, but he had mostly adjusted by Saturday. Hurwitz took some one-on-one practice time with him before the orchestra arrived, and Nasa had also been practicing his part for six weeks.

Nasa (an Anglicized Lebanese name) has been playing piano since he was 3. His parents encouraged his musical education, and he’s performed enough in bands and local musical theater not to suffer from stage fright. He also plays the bagpipes, and has played with 300 bagpipers for 10,000 people at the Royal Edinburgh Military Tattoo at Edinburgh Castle.

“I’ve always had a bit of an inkling that I’d love to be a musician,” Nasa says, “or if I can find some opportunity in the artistic world, or in musical theater or in music, that I would love too. But I did sort of get the ‘real’ degree.”

He was finishing his studies in international relations at the University of Sydney when the cosmic moment happened in May. His friend Scarlett was the one who enthusiastically pushed Nasa’s hand up when Hurwitz, panicking, asked if anyone in the audience was an “amazing sight reader.”

“I owe so much of this to her,” Nasa says. “I really probably would not have done it.”

He played the entire second half of the concert that night. (The hired pianist fell ill and had to leave.) Nasa says he thinks Australians were inclined to root for an underdog — “the audience that night really just wanted it to work” — but for this big L.A. moment, “I think now there’s obviously a bit more of an expectation.”

As the twilight concert began, Hurwitz addressed the sold-out Greek Theatre — a lively crowd filled with yellow dresses — and surprised them by announcing that the “kid from Sydney” was here to play the entire show. Nasa absorbed his ovation, then took his bench in the middle of the orchestra with a little monitor displaying the movie on his piano.

He played the melancholy strains of “Mia and Sebastian’s Theme,” a solo piano motif that Gosling’s character plays throughout the film; he accompanied their flirty “City of Stars” duet, and he performed all of Sebastian’s acrobatic jazz solos — many of them meticulously synced to corresponding shots of fingers on a keyboard.

The film itself was projected over the stage, but monitors on either side showed Nasa and the other live musicians. A young woman in front of me watched his hands, perfectly aligned with Gosling’s, with her jaw dropped. Nasa never missed a note, and he received another outsized ovation after the rousing end credits.

“I’ve thought a lot about opportunity, and how there’s so much talent in the world,” says Hurwitz, reflecting on the moment in Sydney. “And there’s also so much lost talent in the world, talent that just isn’t realized. And I just love that there was this talented guy, who’s a great musician, but he was in school studying something else — because he didn’t know if he could or should go into music. And then there was this opportunity, and he took it, and he showed everybody — and he showed himself — that he can do it.”

Nasa says he’s not sure what he’ll do now that he’s graduated, but one thing he’s interested in is composing for musical theater — or possibly scoring films.
