That's really great to watch.
At 7, that's pretty accomplished playing. It's fun to see a little kid work on his mechanics and fluidity behind the kit...you can see where he's pushed beyond his comfort zone yet still recover, which is a lot of fun when you teach music to a kid - they have an endless desire to keep practicing over and over again until it sounds the way it does in their head...it's just that their little bodies can't keep up with their minds. But you can also see the joy of making music at a young age written all over his face, which is really cool. But age 7, you can also know he's only going to get way better. By age 12, if he stays on it and stays passionate, he could be doing some ridiculous polyrhythmic things. If he gets the right coaching and mentorship, that is. One to watch. .
