From The ice instrument recording project:
Norwegian percussionist Terje Isungset has for years used a variety of organic sound elements in creating music and instruments. (…) Utilizing ice as a source of sound has long been a dream of his, and in year 2000 a serious opportinty came along to explore this possibility. He was commissioned the create a performance piece and composition incorporating the live sound of water beneath a natural frozen waterfall at the 2000 Lillehammer Winter Festival, at minus 15°C degrees and with Palle Mikkelborg og Lena Willemark as participating musicians. (the consert was televised in Norway). This was likely the first public concert ever combining instruments of ice with traditional musical instruments. While making preparations for the Lillehammer concert, Isungset was contacted to help create Sweden’s contribution to the worldwide televised New Years Day Millenium Celebration . In cooperation with sculptor Bengt Carling, Isungset created a set of ice percussion instruments that were played for the whole world to see and hear. [continue, see photos, hear sound samples]
