This is a book very much of our time… Given the fresh and contemporary subject matter, and the feeling of urgency conveyed in the advisory and pedagogical sections of the book that set out clearly how those with access to the appropriate equipment can become active players in the aesthetic and procedural advances described, Redhead takes considerable pains to place her view of music within a historical context in which the subject of her study represents a future that has emerged from the revolutions of a relatively recent past.Redhead combines the investigation of “how to” with significant advice on evaluation, of one’s own practice, of the reception of one’s efforts by listeners and – the true innovation – of the evaluation of active contributors to transmutable operations on the outcomes of their own influence on the music. There is indeed a new aesthetic at work here…One anticipates that a thorough, active reading of Redhead’s book accompanied by completion of the tutorial tasks will lead on to a longer engagement with both the book’s own Companion Website and the programs and instructional material additionally accessible.
