More than 20 years ago, three musicians in their 20s — graduates of the Central Conservatory of Music in Beijing — enjoyed spending time together as close friends. Then, during one seemingly ordinary dinner, everything changed.

On a whim, they decided to form a trio — a spontaneous spark of a musical dream was ignited around that table. No one knew if it would fade or flourish. But that impromptu decision marked the beginning of a musical journey that has now lasted for two decades.

Today, they are known as the DNA Trio — one of China's most acclaimed chamber music ensembles — comprising pianist Zhang Jialin, now a professor at the Central Conservatory of Music; violinist Zhang Jingye, also a faculty member at the conservatory; and cellist Song Zhao, an independent artist.

This year, as the DNA Trio celebrates its 20th anniversary, the musicians return not only to the stage, but also to the roots of their artistic identity. From Saturday to Aug 9, the trio will perform one concert each month, systematically presenting all eight of Beethoven's piano trios.
