This is The Trees by Rush on Rockband 2 with Jared (8 yrs old) on drums. Expert mode means that he is required to hit the drums exactly the same frequency as the real drummer Neil Peart. He doesn’t get it perfect at all (89% accuracy), but still I am really impressed.
He is just getting better and better. Soon, I will have a video of Ethan playing ukulele, which he is becoming pretty good at. Still very excited for Rock Band 3.
