When an onstage emergency threatened to halt a sellout screening of La La Land in Sydney, the audience watched an unexpected piece of theater unfold off-screen. What began as a routine live-to-picture concert turned into a nail-biting improvisation that ended with a standing ovation and a stunned conductor.
With the film projected behind them and the orchestra ready to play, the evening at Darling Harbour theater stretched into an anxious pause. A last-minute illness sidelined the scheduled pianist, and the composer-conductor on the podium made a surprising request: was there a trained pianist among the 2,500 people watching?
Chaos backstage and a bold request from Justin Hurwitz

The performance stalled as the orchestra waited. What started as a brief interruption grew into a long pause—20 minutes became 30, then 40—while crew members scrambled to find a replacement. With no firm answer coming from the wings, Justin Hurwitz, the Oscar-winning composer conducting the score, stepped forward to face the audience and outline the dilemma.
- Hurwitz explained the situation and asked for a volunteer who could sight-read the La La Land score.
- He emphasized the scale of the risk: the music is tightly synchronized with the film and features demanding rhythms and a critical synth solo.
- With 2,500 people in the hall, Hurwitz decided to take a chance on the crowd.
From the stalls to the piano: Sterling Nasa accepts the challenge
Among those watching were Sterling Nasa and his friend Scarlet. Encouraged by Scarlet, Nasa raised his hand and was chosen to take the seat at an electronic piano tucked into the orchestra pit. He wasn’t a professional concert pianist—his musical training was modest and he hadn’t rehearsed the film’s arrangements—but he did have enough confidence and sight-reading ability to try.
Nasa walked onstage nervous but determined, aware that the score required flawless timing to match the actors on screen. He’d admired Hurwitz’s work but had never played these pieces live with a full orchestra.
The high-stakes sections: what made the piece so difficult
Several elements made this a risky substitution:
- Precise synchronization: the orchestra was accompanying a film projection, so timing had to match on-screen action.
- Complex notation: the score features rapid passages and tight harmonies that demand strong sight-reading.
- The synth solo: a specially composed synth line by John Legend in one scene needed split-second coordination with the visuals.
Faced with those hurdles, both Hurwitz and Nasa knew the moment could go either way. Hurwitz asked a few quick follow-ups to confirm Nasa’s comfort with sight-reading, then welcomed him to the piano amid applause.
Improvisation and quick thinking saved the performance
When the critical synth passage arrived, Nasa hesitated—then made a creative choice. Rather than trying to reproduce the exact studio line note-for-note on first sight, he improvised a convincing alternative that fit the scene and the orchestra’s energy. The gamble worked.
His improvisation held the film’s momentum and won the audience over; the hall that had fallen quiet during the delay erupted as the orchestra and new pianist navigated the rest of the score together.
Backstage reactions and the aftermath
After the final bow, Hurwitz and Nasa exchanged handshakes and surprised smiles backstage. The conductor admitted he was still processing what had happened, calling the decision a gamble that ultimately paid off. Audience members and musicians alike were left buzzing at how an ordinary theatergoer rose to meet an extraordinary moment.
- Hurwitz later said the choice to ask the crowd was born out of necessity—and a bit of faith in the power of live performance.
- Nasa described the moment as equal parts terrifying and exhilarating, noting that improvisation was key to getting through the toughest passage.
- Theaters and orchestras watching the clip have since praised the quick thinking of everyone involved.
