"The exhibition "adonnaM.mp3" is concerned with the phenomenons of audio filesharing, peer- to- peer- networking and the mp3-standard. It analyses the drastic changes which the use of this digital tool is effecting in society, the economy, art and design. File sharing is revealed as a contemporary vehicle that provides the basis for a new means of communication and is also an instrument of creative expression. Selected designerworks about the mp3-topic are enhancing the exhibition with sensual facets."
Looks like I missed another interesting exibition in Frankfurt. Nevertheless there is lots of interesting content, including an article on the history of MP3, available on the official homepage.
