Another great lesson thanks to the kind folks over at the Jazz @ Lincoln Center's Jazz Academy. Here's the Master brush player Jeff Hamilton himself talking and demonstrating some very important, basic brush concepts:
This idea of playing the brushes laterally or "side-to-side" as opposed to strictly an up-and-down motion was one introduced to me (via Jeff incidentally!) about ten years ago or so from an article he wrote for the PAS publication Percussive Notes (see "You've Got to Be Pretty to Play the Brushes" in Percussive Notes, February 2004). This really opened up my own brush playing and changed things in a positive way. I don't always play way this but it certainly adds another dimension to one's brush playing and it really helped me. Check it out.
