CREAKS

Glaciers greet their audience with iceberg melodies, sending friendly signs to their hosts. However noisy and intimidating, the birth of a block of ice is a declaration of hospitality, a permission to remain in the territory, like a special ticket to enter a restricted area. As it begins its symphony, the orchestra of giants begs the guests to enter into the conversation. Glaciers have a visible sound signature; the cries of icebergs falling into the water are their ‘visual voices’.
