Veteran musician Traithep Wongpaiboon, 45, managing director of Kantana Sound Studio, made headlines last year for his sound editing in Wong Kar Wai’s film The Grandmaster, which won him a gong in the Golden Reel Awards, the self-described Oscars for sound editors. Now he’s plotting his music career comeback next month as one half of the pioneering electro-pop duo Kidnappers, after 10 years off the scene.
