On 7 August 2026, the Brothers in Harmony Symphony Concert took place in Karlovy Vary, the historic spa city in the Czech Republic. Sixteen-year-old pianist Kevin Tan and his 13-year-old brother, composer Carey Tan, shared an evening that brought together the classical tradition and a new generation of musical expression. Kevin performed two major works of the piano concerto repertoire — Beethoven’s Piano Concerto No. 5, “Emperor” and Rachmaninoff’s Piano Concerto No. 2 — while Carey presented his original Symphony No. 3, The Rise and Fall of AI Humanity. From Beethoven and Rachmaninoff to a young composer’s musical reflection on artificial intelligence and the future of civilisation, the evening became more than a concert: it became an encounter between the past and the future, between artistic tradition and contemporary thought.
For Kevin, the evening presented an exceptional musical and physical challenge. Beethoven’s Emperor Concerto, with its grandeur, heroic energy and architectural scale, demands not only technical strength but also stamina, concentration and a mature understanding of musical structure. Yet for Kevin, this was only the beginning. In the second half of the concert, he returned to perform Rachmaninoff’s Piano Concerto No. 2, entering a very different emotional world of introspection, melancholy, passion and hope. Performing two works of such scale in one evening required him not simply to sustain his physical and technical control, but to create two completely different musical languages. He met that challenge with remarkable stability, while communicating the contrasting emotional and spiritual character of each concerto.
The audience responded enthusiastically. After Beethoven’s Emperor Concerto, applause continued for several minutes, and when the final movement of Rachmaninoff’s Second Piano Concerto came to its powerful conclusion, many listeners rose to their feet. The audience included not only local residents but also visitors from Germany, Austria and other parts of Europe, many of whom were experienced classical music listeners familiar with both Beethoven and Rachmaninoff. After the concert, a number of them stayed behind to speak with Kevin, commenting not only on his technique but also on the emotional strength, character and expression of his playing.
Yet one of the most memorable moments of the evening came after Carey’s original third symphony, The Rise and Fall of AI Humanity. Written as a five-movement musical narrative, the work imagines the rise, prosperity, disorientation, collapse and eventual renewal of an artificial-intelligence-driven civilisation. Rather than presenting AI simply as an external threat, the symphony asks a more fundamental human question: as technology assumes more of our labour, decision-making and responsibility, will people still retain independent thought, genuine emotion, spiritual freedom and a meaningful connection with the natural world?
Across its five movements, the work traces a civilisation initially transformed by extraordinary technological efficiency. Human life becomes easier as machines take over more functions, yet people gradually begin to miss the difficulties, choices, effort and even pain that once formed part of genuine human experience. The music then turns towards nature and the universe, expressing a renewed longing for forests, rivers, sunlight and the physical world. Eventually, the technological civilisation begins to collapse, and from its ruins humanity must rediscover its relationship with other people, with nature and with itself. Technology is not rejected; instead, the work raises the idea that technology should serve humanity rather than cause humanity to lose its sense of identity and purpose.
Although the symphony was conceived as an exploration of the future, it unexpectedly awakened the memories of one audience member’s past. A German woman approaching 90 years of age, who had lived through the Second World War and witnessed Europe rebuilding after the destruction, was profoundly moved by the performance. As she listened to the musical progression from the construction and prosperity of civilisation to collapse, destruction and renewal, she did not hear only a story about artificial intelligence. She heard echoes of her own life: war, a shattered homeland, social upheaval, ruins, rebuilding, and the gradual restoration of ordinary life, order and hope.
By the end of the symphony, she was in tears. Afterwards, she sought out Carey and spoke with him for a long time, asking about the ideas behind each movement and why he had chosen to write about the rise, destruction and rebirth of civilisation. What surprised her most was his age. She explained that she might have understood such a work coming from a 60-year-old composer who had personally experienced war, social upheaval and reconstruction, but she found it extraordinary that a 13-year-old could write music that brought back such powerful memories of her own past. She told Carey that, through a symphony about the future, she had found herself looking back across her own life.
That encounter captured something at the heart of the evening. A 13-year-old composer had used music to imagine a civilisation decades into the future, while a woman more than 70 years older heard in the same music the history she had already lived. They came from different countries, different generations and entirely different life experiences, yet the same piece allowed them to meet on an emotional and spiritual level.
Perhaps this is one of music’s most remarkable qualities. A composer may begin with a particular idea, but once a work enters the concert hall, it no longer belongs only to its creator. Different listeners discover different meanings within it. One person may hear the future, another may remember war; one may hear destruction, another renewal. A piece of music can awaken memories that words cannot reach and create connections between people who otherwise share neither language nor history.
The Karlovy Vary concert therefore became more than a showcase of two young musicians. Kevin entered the contrasting worlds of Beethoven and Rachmaninoff, demonstrating the discipline and emotional range required to perform two monumental piano concertos in a single evening. Carey, meanwhile, used an original symphonic work to engage directly with questions facing contemporary civilisation: technological power, human responsibility, our relationship with nature, and the kind of future humanity wishes to create.
By the time the final applause faded, the lasting impression of the evening was not simply one of technical achievement. Classical masterpieces and an original contemporary symphony, a 16-year-old pianist and a 13-year-old composer, a young musician imagining the future and an elderly listener remembering the past had all converged in the same concert hall. What remained was a powerful example of how music can cross generations, cultures and national boundaries — and how a work written by one person can unexpectedly become part of another person’s life story.
