I may be a few year off with this review, but this 2009 documentary will now be a highlight of my college-level educational technology courses. The discussion of fair use and copyright is a difficult topic to teach. I know much more than the teachers and future-teachers I guide, but I am a far cry from an expert on the topic.
This movie does an excellent job presenting the opinions of highly regarded musicians who created original music, and those who "sample" that music. Well produced, thought-provoking, and highly educational. The online resources and curriculum at PBS are extensive. To top it off, the video is now available in the NetFlix Instant Queue.
