I watched this tonight on YouTube, and while I found some of the information very interesting, the guy came off as an arrogant wanker. He kept saying so and so is "the greatest ambient musician since Eno" (he said this about Biosphere!! Come on, really???) and such and such is "the greatest ____ in the history of this planet." He spent the first hour talking about classical music and early synthesizers, which was a bit much. The most interesting part was the end where audience members got to ask questions. The first person asked why Klaus Schulze was merely mentioned once. He said he didn't have time. Well why the hell did you waste an hour on Debussy and Satie and early dinosaur electronic instruments like the trautonium and theremin??? But the BEST question was by Mr. Loren Nerell, who so eloquently nailed Mr. Prendergast with his glaring omission of the Southern California (and Northern as well) ambient giants like STEVE ROACH, ROBERT RICH, MICHAEL STEARNS, both in his "comprehensive" book and in the lecture. He said he "wasn't familiar with all ambient artists." WHAT?? He mentioned a San Francisco DJ named DJ Shadow, and called Geir Jenssen the greatest ambient musician since Eno, but had never heard of Roach and Rich??? He talked about the Grateful Dead and Jimi Hendrix and wasted 10-15 minutes playing their music, yet couldn't even mention the above. What an IDIOT! God, I'm glad I didn't attend that lecture, I would've had a fit. No Tangerine Dream??? At least he paid tribute to Pete Namlook, but the glaring omissions were just unforgiveable.
