I love Imogen Heap. I love her music - I write to it whenever I get Writer's Block (shush! Keep that Under Your Hat!), and just found this sound that is part of her new album where, every 3 months, she will release a new song and, at the end of the project (3 years), she will release the album in CD form or if you prefer digital download, you could download each song as they are released.
And this is Imogen's first song within this project. And it took her TWO WEEKS TO MAKE!
