When I see a rainy day, I think that nature is crying. A tide is nature breathing

THE BBC MUSIC MAGAZINE INTERVIEW Tan Dun | The Chinese-American composer has risen from humble origins to global success, yet his concerns - balance, humanity and the natural world - remain the same, writes Claire Jackson

The contrast between the two voices - one gravelly and earth-bound, the other high and gurgling was extreme. The colours were further enhanced by the range of instruments on the Royal Festival Hall stage; the London Philharmonic Orchestra - with alto flute, celeste and no fewer than four percussionists - supplemented by a xiqin, a traditional Chinese three-stringed bowed instrument played vertically like the cello. The player was Batubagen, a musician from the Inner Mongolian area of Bairin Right Banner. He was one of several special guests that composer and tonight's conductor - Tan Dun had invited to give the UK premiere of Buddha Passion, the 2018 work co-commissioned by the Dresden Music Festival, New York  Philharmonic, Los Angeles Philharmonic and the Melbourne Symphony Orchestra.

When Bach composed his St Matthew Passion (first performed in 1727), he was following a centuries-long tradition of dramatising the Passion of Christ. Music had often accompanied Holy Week celebrations, eventually developing into a more standardised oratorio based on Gospel texts. Composers were compelled by the subject (Telemann wrote 44 Passions; Bach composed two others), and the form continues to be a mainstay of choral music - albeit in some unusual guises. In 2000, Helmuth Rilling commissioned four new Passions - from Dun, alongside Wolfgang Rihm, Sofia Gubaidulina and Osvaldo Golijov - to mark the 250th anniversary of Bach's death. For his work, Dun placed water at the centre of his piece (see panel, p35).
