Tan Dun’s Water Passion After St. Matthew, given last night by Soundstreams at Trinity St. Paul’s is very Tan Dun. The work is in nine movements and scored for chorus, soprano and bass-baritone soloists, violin, cello, electronics and lots of percussion. And bowls of water and rocks. The texts broadly follow the Passion story finishing with a final Resurrection movement in which water is the symbol of rebirth, recycling and spiritual completeness. There are also ritual elements. Bowls of water laid out in a cruciform pattern are lit from beneath. The musicians change position and the players, especially the percussionists, perform hieratic gestures with the water bowls and their contents. It also involves a complex and dramatic lighting plot.
