Commuters at London’s iconic King’s Cross Station were treated to an unexpected burst of festive energy this week as viral pianist Julien Cohen – best known for his Bohemian Rhapsody flashmob in Paris – delivered a series of dramatic live performances in his first-ever UK flashmob. But this time, the spectacle came with a groundbreaking twist: the reveal of the brand-new ROLI Piano.
What appeared at first to be a traditional upright piano quickly transformed into something else entirely. As the vintage shell opened, it unveiled the next generation of music tech – the new ROLI Piano, paired with the ROLI Learn App and Airwave, the brand’s AI-powered learning tool. Airwave introduces real-time hand-tracking designed to reinvent how beginners and seasoned players alike learn piano.
The concourse instantly shifted from commuter hub to concert venue as crowds gathered to watch the spontaneous spectacle. The atmosphere echoed the viral buzz of Cohen’s previous performances, but with an added sense of discovery thanks to ROLI’s innovative tech.
An Electric Rush-Hour Showcase
Throughout the busy evening rush, Julien Cohen delivered several show-stopping sets, including a fan-favourite rendition of “Berghain” by Rosalía – a UK Top 40 hit and one of the standout tracks from her latest chart-topping project.
In true flashmob fashion, “commuters” suddenly joined in—revealed to be planted performers—sparking applause and drawing even larger crowds from across the station.
A Star-Studded Line-Up and Unexpected Talent
The musical momentum continued as acclaimed pianists and composers Karim Kamar and Toya Delazy took to the keys, adding their own unique flair to the experience. Yet some of the biggest surprises came from everyday passers-by.
With the help of the ROLI Piano’s light-up keys and Airwave’s real-time AI hand guidance, complete beginners were able to step up and learn to play their first song on the spot. The activation brought together experts, hobbyists, and first-time players in a shared moment of joyful public music-making.
Reinventing How People Learn Piano
This flashmob wasn’t just a performance—it was a live showcase of ROLI’s mission to transform how people learn and experience piano. The combination of expressive hardware, intuitive in-app learning pathways, and Airwave’s advanced hand-tracking AI signals a new era for accessible music education.
