British teenage brothers close international summer tour with sold-out Cadogan Hall concert
13-year-old composer Carey Tan presents AI symphony with the Philharmonia Orchestra, while 16-year-old pianist Kevin Tan performs Beethoven and Rachmaninov in the same evening
London, 8 September 2026 — British teenage brothers Kevin Tan and Carey Tan brought their 2026 Brothers in Harmony summer international concert tour to a sold-out close at Cadogan Hall, London, on Monday evening, performing with the Philharmonia Orchestra under the baton of Geoffrey Paterson.
The concert, Brothers in Harmony: Where Classics Meet New Voices, brought together two contrasting but connected musical worlds: the great piano concerto tradition and new symphonic music by a teenage composer. Sixteen-year-old pianist Kevin Tan performed Beethoven’s Piano Concerto No. 5 in E-flat major, Op. 73, known as the “Emperor” Concerto, and Rachmaninov’s Piano Concerto No. 2 in C minor, Op. 18. His younger brother, 13-year-old composer and marimba performer Carey Tan, presented two of his own original symphonic works: The Cries of War and The Rise and Fall of AI Humanity.
Carey also introduced the concert from the stage and performed marimba within his own orchestral works.
The Cadogan Hall performance marked the final concert of the brothers’ 2026 summer tour, following performances in London, Beijing, the Czech Republic, Romania and Austria, including Vienna’s Musikverein. It was the sixth major concert of their summer season and the culmination of an international journey that has seen the brothers work with professional orchestras across several countries.
A teenage composer writing about AI without using AI
Carey Tan’s Symphony No. 3, The Rise and Fall of AI Humanity has attracted particular attention for its subject matter. Written by Carey when he was 12, the work imagines a future civilisation shaped by artificial intelligence: its rise, dependence on technology, loss of contact with nature, collapse and eventual attempt at renewal.
The symphony was composed entirely without the use of AI.
In the work, Carey does not present artificial intelligence simply as a threat, nor as a technological novelty. Instead, the music asks whether human beings can remain creative, responsible, emotionally alive and connected to nature in a world increasingly shaped by machines.
On the morning of the Cadogan Hall concert, Carey was interviewed on BBC Radio 4’s Today programme about the work, its ideas and the relationship between music, AI and humanity. Later the same day, he was also interviewed by BBC World Service’s Newshour, bringing the story of his music and the Brothers in Harmony tour to an international audience.
A sold-out London finale
The Cadogan Hall concert played to a sold-out audience and received an enthusiastic response. Carey’s two symphonic works drew strong reactions from the audience, with applause and cheers following several movements and standing ovations at the end of each symphony.
Many audience members remained at the venue long after the concert ended, speaking with the brothers and reflecting on the emotional impact of the music. Several older British concertgoers described being deeply moved by Carey’s treatment of war, nature, technology and the future of human society.
The Cries of War, Carey’s second symphony, reflects on conflict, memory, trauma and the fragile hope for peace. Rather than depicting one specific war, it asks what war leaves behind in human lives, societies and memory.
The Rise and Fall of AI Humanity turns towards one of the defining questions of the present age: how artificial intelligence may reshape human civilisation. Its central concern is not whether machines will defeat humans, but whether human beings may lose their creativity, judgement, responsibility and sense of wonder if they become too dependent on technology.
Beethoven, Rachmaninov and new music on one stage
Kevin Tan’s role in the evening placed him within the great classical concerto tradition. Performing Beethoven’s Emperor Concerto and Rachmaninov’s Second Piano Concerto in the same evening is a major challenge for any pianist, requiring technical command, stamina, structural control and emotional range.
At 16, Kevin’s performance drew praise from audience members for its maturity, sensitivity and command of two very different masterpieces. The combination of Beethoven, Rachmaninov and Carey’s original symphonic works gave the evening its central identity: established classics heard alongside new music responding to the questions of the present.
The concert’s title, Where Classics Meet New Voices, reflected the brothers’ different but complementary artistic paths. Kevin approached the evening through two of the most powerful works in the piano repertoire, while Carey used the orchestra to explore contemporary themes including war, peace, artificial intelligence, nature and the future of civilisation.
Next stage for Brothers in Harmony
Following the success of the 2026 summer tour, Kevin and Carey Tan are preparing for the next stage of Brothers in Harmony. The project is expected to continue in the 2027 season, with further international performances planned and larger UK concert platforms under discussion, including London’s Royal Festival Hall.
Carey has also completed four further symphonic works: Symphony No. 4, Journey Through the Universe; Symphony No. 5, Seven Doors to Eternity; Symphony No. 6, Elevated; and Symphony No. 7, Spirit of All Things, a choral symphony. These works are expected to form part of the next phase of the brothers’ concert journey.
For Kevin and Carey Tan, the sold-out Cadogan Hall concert was both the conclusion of a summer tour and the beginning of a new artistic chapter. One brother brings extraordinary focus to the great piano repertoire; the other is using symphonic music to think about the future. Together, they represent a rare musical partnership: two British teenage brothers using one of the oldest art forms to speak to some of the newest questions of the modern world.
