Inside a giant igloo in a snowy Norwegian village, the sound of a horn rings out, warming the mood of a freezing audience, huddled together in -24 Celsius.
But the four musicians performing are even colder: the instruments they are playing are all made of ice.
The xylophone, claves and wind instruments have been painstakingly carved from ice blocks extracted from a frozen lake, and are now part of a finger- numbing performance at the 13th Ice Music Festival in the mountain village of Finse.
The problem is, the longer the musicians play, the more the instruments start to disintegrate.
It is not an easy task “to perform on instruments that are melting while you play them,” says percussionist Terje Isungset, also the founder of the festival.
Wearing thick wool gloves, he blows warm air into his ice-sculpted horn, illuminated under blue and turquoise lights.
Next to him, a singer with an angelic voice covers her mouth with a scarf to stay warm, while a bass player removes his gloves so he can pull the strings on his ice-made instrument.
