This concert was part a strand of electronic music events at Tate Modern which explores the contemporary face of digital music. It featured performances by leading electronic musicians and performers, Akufen (Canada), Janek Schaefer (UK) and Golan Levin (USA).   This music event complemented the international symposium, user_mode, which examined emotional engagement within interactive art and design. It is a collaboration between Central Saint Martins College of Art & Design and Tate Modern. In tandem with its exploration of the emotional dimension of electronic music, this performance event showed ways that interactive techniques can dissolve the boundary between musician and listener, artist and spectator, and producer and user.
