Music videos today sample and rework a century's worth of movies and other pop culture artifacts to offer a plethora of visions and sounds that we have never encountered before.    As these videos have proliferated online, they have become more widely accessible than ever before. In Digital Music Videos, Steven Shaviro examines the ways that music videos interact with and change older media like movies and gallery art; the use of technologies like compositing, motion control, morphing software, and other digital special effects in order to create a new organization of time and space; how artists use music videos to project their personas; and how less well known musicians use music videos to extend their range and attract attention.   Surveying a wide range of music videos, Shaviro highlights some of their most striking innovations while illustrating how these videos are creating a whole new digital world for the music industry.
