One of my research interests is the history and development of music technology and its use in Norway, and I have published CDs and texts on several arenas from this research. And now, I have published a book “Elektrisk lyd i Norge” (Electric Sound in Norway) which sums up, explains and describes the main tendencies of this development from the frail beginnings in the 1930s and up to approximately 2005. The bulk of the text is placed under four headings: Electricity and radio, With tape and scissors, Keyboard and mouse, and Control and participation. The book explains how the technology-based music fits into larger cultural and social processes of development.
