Hi there
His style is very sober, but effective. At times (very) hard to understand what he wants you to do. Video obviously can hardly capture his technique, or even in general Aikido.
Last weekend he did a seminar in Holland and Alain explained why he typically does not allow video recordings of his lessons. "Why would it make you happy that your adversaries can study your capabilities ". "This, to me, sounds ridicolous".
So enjoy the videos
What you see is not what you get.
What you get you might not understand.
