Ben Katchor and the New York Comics & Picture-story Symposium
The New York Comics & Picture-story Symposium is a weekly symposium for artist/writers working in various text-image forms: comics, picture-stories, animation, etc. at which to present and critique current work. Organized and presented by the Ben Katchor, one of Amerikas most important cartoonists. Ben is also a Professor in the Illustrations Department at Parsons School of Design in New York.
Ben Katchor himself gave a lecture at Hannover recently, a video of the event might be online soon.
Until then I recommend watching some of the lectures by great Artists like Anders Nilsen or Simon Hanselmann, which are available online.
