A concert with instruments made of ice

Deep in the Jostedalen glacier in Norway, musician Terje Isungset puts on an annual concert played on instruments made of ice. It just completed its 2018 run, though they had to move further north this year to an icy lake due to warming temperatures.

Here's a nicely-produced clip from the 2014 concert.
