DE: Insight on the Theorie of Music Videos

Looking for media theories that come to the help of defining Live Cinema one can not ignore the genre music video. It has helped the Live Video Scene of the 70s to evaporize and still has the power to sell millions of music copies. Looking through the net to look for any theory overviews that define Music Videos I come across a swedish lecturer named Sven E Carlsson. He has a PDF up for everyone to enjoy and get that short view on the theoretical side of Music videos.
He also links to the Music Video Archive - which must be the most complete archive of music videos on the net (around 50.000 description in the database) - no the actual videos are not on there of course - just information on who did what when with who and where.
