Prof. William Fisher is making his Harvard Law School on Copyright available gratis through edX. Below you will find an excellant two hour discussion of copyright from the perspective of creators. Among the four speakers is John Drake of Harmonix, the company that created the “Guitar Hero”, “Rockband” and “Dance Central” series. Those games are particularly interesting because the genre is itself a form of re-mix of the creative works of others.
All of the speakers are very worthwhile. Most of the legal perspective comes from Dale Cendali of Kirkland & Ellis. FYI John Drake is introduced @ 7:20 & speaks @ 30:57. Dale Cendali is introduced @ 8:20 & speaks @ 36:44
