Bangkok's classical music scene has a story worth following. Siam Sinfonietta, the city's youth orchestra, just wrapped its 2025/26 season with a heavyweight programme at King's College Great Hall: Sibelius' Violin Concerto and Beethoven's Third Symphony, the Eroica.
What makes this orchestra unusual is that it was founded by young people themselves rather than by any institution. Composer-conductor Somtow Sucharitchakul started it 15 years ago with a simple pitch: a 'kids' orchestra' that could play real music. Since then it has earned critical notice abroad and toured some of the world's great concert halls — which is why hearing them tackle Mahler, Strauss or Stravinsky rarely feels like a student recital, even though nobody on stage is over 25.
For this finale, many of the players are already professionals with the Royal Bangkok Symphony Orchestra and the Thai Philharmonic. The Sibelius fell to violinist Bhaskar Javadihirih, whose polished delivery of the movement's song-like core set the tone; Somtow then introduced guest conductor Trisdee na Patalung, internationally recognised as one of Thailand's leading conductors, to take the Eroica.
Trisdee, known for his devotion to authentic performance practice, offered something closer to a period-informed reading: brisk tempos, and a funeral march closer in spirit to Roger Norrington's radical 64-minute Beethoven cycle than to the sweeping grandeur of Golden Age conductors like Furtwängler. Where Norrington prioritises precision, Trisdee went for sweep and drama — a hard-charging finale that had the orchestra playing flat-out, and one of the more thrilling Eroicas this reviewer has heard live.
The bigger picture is bittersweet. The orchestra's model means a natural turnover every seven years or so as members age out and move on to professional careers — Somtow calls the season finale a farewell of sorts. Bhaskar will be missed; applications for next season are reportedly strong. The faces will change, but the ambition, it seems, stays the same.
For travellers, this is a genuinely good reason to time a Bangkok visit around the concert season. A top-tier youth orchestra playing challenging repertoire in a striking venue, at local prices far friendlier than a London or Vienna ticket, is a rare cultural bonus on a Southeast Asian itinerary.
