The world's only festival of ice music, will be held in Geilo, Norway, January 16-19, 2014. At last year's festival, we followed the process as sculptors and musicians made the instruments from lake ice, recorded the otherwordly sounds they produce and captured the final haunting performances in a purpose-built auditorium made out of snow.
