Drummer Matt Garstka and "displacement"
This guy is a beast! The ideas Matt shares in this short video could fill a lifetime of practice. Although what he's playing sounds pretty complicated, with a little bit of patience, it's something you can easily apply to your own playing.
To start, pick a simple groove (start really simple) and try shifting it either forwards or backwards by half a beat — like in the example below. It'll sound and feel strange to play at first, so it's a good idea to practice it to a click and to count as you play. Once you feel comfortable playing your new displaced groove, try alternating between it and the original version.
As Matt demonstrates in the video, you can have a lot of fun with this idea!
