A great series of brush lessons today from the Berklee College of Music's Jon Hazilla. As he explains in the first video, these are applications of Joe Morello's seminal work Master Studies using combinations of lateral strokes with the brushes (inspired by his lessons with Joe Morello, Mel Brown and Jeff Hamilton).
There is lots of great information here. These are great concepts and techniques that will only deepen your approach to brush playing. Thanks for sharing these Jon!
