Spring has finally arrived, but I stumbled over two very interesting adventurers dealing with the sounds of ice that I find worth sharing. Marlin Ledin travelled the snowcovered Apostle Islands of Lake Superior in Northern Wisconsin by bike (!) and did some fantastic ice recordings on his way. And Cheryl E. Leonard reports from her journeys to the Palmer research station in Antarctica where she collected sounds for her musical work. On Saturday she will perform at the Activating the Medium XIII : Ice festival in San Francisco. In her blog some fine ice recordings can be heard, next to recordings of seals, pinguins and other stuff, which has been also released on the CD Chattermarks.
