Anthony Seeger, Distinguished Professor of Ethnomusicology and Director of the UCLA Ethnomusicology Archive, imparts some of his considerable musical knowledge, and also a song, when he delivers the prestigious 110th Faculty Research Lecture. He looks at the opposing positions of "Don't pirate my music" and "Knowledge wants to be free" to discuss the more general point that copyright law is only one way among thousands that societies regulate the transmission of and access to knowledge. The lecture is preceded by the UCLA Bluegrass and Old-Time String Ensemble singing, "This Land is Your Land." (#23417)
