Finally found this with sound. Kyle Balda (once of Pixar, teaching summer school at Gobelins).
*little bit later
Had a chance to watch it. Interesting, it reminds me of the splinecast with Doug Sweetland (I think) where he talked also of starting just with the root musically to the dialogue. Makes me think that was the common technique at Pixar as they built there way up through those listerine and lifesaver commercials, when CG was still new. Animation Mentor really pushes the pose to pose style, which is very strong and can give good reliable results (probably easier to teach also), it's interesting to see this different style at obviously an equally high level.
Had me smiling that he was talking bout the same stuff I had just been pondering, namely that the fact that the audience is going to be watching the eyes and face, so get into it as quick as you can so you don't overwork the body.
Also funny when he says "sometimes you need a blink just to keep the character alive" which is a complete contradiction of Shawn Kelly's recent post. (I side with Kelly)
