This lecture took place at the Gifford Auditorium, Syracuse, 23rd April 1975.
Don is fairly quiet throughout the lecture; when asked a direct question he gives not so much oblique answers as abstract statements beamed into his brain from who-knows where. When asked to talk a little about Trout Mask Replica, Don instead quotes sections from Sam With The Showing Scalp Flattop. Unmissable, but not particularly helpful.
Frank Zappa, who does the vast majority of the talking, makes considerably more sense with his genuinely insightful ruminations on the workings of the music industry.
