"Glacier" by Glacier, literally: Thanks @Glacier!

Ice Records by Katie Paterson

Katie Paterson recorded the sound of 3 glaciers (Langjökull, Snæfellsjökull and Solheimajökull) in Iceland. She then pressed those recordings on ice records made of melt water from those glaciers. The records were played on 3 turntables and it took almost 2 hours till they were completely melted. You can download one here.

This is weird, right? Check out the original post. Thanks to cars & trains for the tip!
