This is fun, Diltz and Burden give a great background to both their work in creating LA album covers in the 70s (they kept film records as well as copious diary notes) and also how the scene was then. Several protagonists (Webb, Browne, CSN, etc) help out and the whole deal is thoroughly entertaining. Other acts included are Pryor, Cass, America, you may be getting the idea. Best of all is the sequence describing how the Jimmy Webb album Land's End had its cover made. A frightening glider (sail plane) ride in the California mountains resulted in a crash in the middle of nowhere and both Webb and Diltz were lucky to escape with their lives. See this before you go to LA, it's a great travelogue as well.
