Drummers love to share ideas and knowledge even at thew highest levels. Many of us have been to clinic after clinic (Danny Gottlieb most recently at Juniata College) where top notch drummers share with us details of what got them to that high level.
Drummer Billy Ward has put up a link on his web with rehearsal footage of his trio. He actually is a member of the Pearl Drummers Forum even though he is a DW sponsored drummer. He posted on PDF this offer.
You can download video or audio and pay what ever you want ! As he puts it, it cost musicians to play and produce it so he needs to cover some costs - but you can pay anything you want.

I haven't had time to watch it yet, but I've seen Billy on video before and I will when I have the time.
Billy also has his own discussion forum. I'm a member there as well. I would advise drummers to check out his forum.
