Our challenge was to reassert Walkman's music credentials. To do this, we decided to engage users by encouraging them to make and mix music on the Walkman® Project website.The site is a triumph of sound design. It hosts a specially commissioned piece of music broken down into separate parts. Users are able to download any part of the music, e.g. rhythm, bass or melody and then re-record their own version using any instrument they like. They can then upload this to share with others.Users can also mix up to four contributions from others together to create their own unique interpretation of the original piece. The site integrates neatly with the above-the-line concept that explores a piece of music produced by many instruments, each playing a small part.The site answered Sony's brief perfectly - to produce a literal demonstration of how Walkman® delivers music like.no.other.
