This is a little bit off-topic, but probably interesting to some anyway:
"In early February 2001, Terje Isungset went to The Ice Hotel
in JUKKASJÄRVI , North Sweden, to record the first ever all ICE music CD.
All instrument were to be made from ice.
(shaped by ice-sculptors Bengt Carling, Arne Berg and Åke Larsson in cooperation with Isungset)
A number of percussion instruments, as well as ice harp and ice trumpet!
(played by Terje Isungset, Iro Haarla og Arve Henriksen, respectively)"
