Here is a video on the push-pull hand technique I use and its application on the drum set.
The exercises in this video are from my book Advanced Coordination for Drum Set and Hand Percussion. You can read more about the book here: http://www.acousticbarn.com/rickspercussionsite/books.html
and order it from me at [email protected]
The drums I am using are Doc Sweeney African Olive wood stave shells. I have just started an endorsement deal with this company and their drums are incredible. You can read more about them here: https://docsweeneydrums.com
