well, the two tricks are not the same thing. The Calvin Warren thing looks to be some wierd drum stick angle hit. I don't think it is really anything more than that. However, Calvin posts on this board so hopefully he will see this and enlighten us.
Now, the Greg Jackson thing is the claw I THINK. Personally, it is hard for me to tell because of the video angle. If it is the claw then there is a thread in the snare playing forum that explains how to do it. If that isnt what he is doing...I dont know what to tell you.
