This is the first one I saw by them. It was a demo at BB. I was super amazed. Couple years later I remembered that demo and googled balls shooting at drums lol. I found animusic and bought one and two. The really cool thing is that even people who aren’t musicians can see how instruments work. Especially when they come alive.
The YouTube link will give you an idea but obviously will sound like, well....YouTube.
Anyway, I love it that your kids dig music. Mine do too, and thought I’d throw this out.
Sorry for the detour. Although, dsu would do an amazing job with some of these tracks. My favorite...
