wow. reminds me of that record Weather Report by Chris Watson
rdrb:
Katie Paterson recorded the sound of 3 glaciers (Langjökull, Snæfellsjökull and Solheimajökull) on Iceland. She then pressed those recordings on ice record 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 listen to one here. (via Ice Records - today and tomorrow)
