Woodkid is a video director and musician who I really admire and his song "Iron" was a piece of brilliant music. It's a tune that really shouldn't be touched by anyone else, but I think Dream Koala did a decent job and probably one of the select few who could pull this off. As a thank you to the fans for 100k views on his "Odyssey" video he decided to cover this and make it available to download. So, on his version he took the haunting vibe of the original and expanded on that. It's different, but in the best way possible.
