This 4-year-old drummer kid will knock your socks off (literally). Here is one of many videos of him. His talent is absolutely unbelievable. Off-tempo beats, changes in tempo, fills that match the music, and timing! My gosh his timing! Some kid geniuses go crazy with fills and such, but Igor patiently shows real talent by applying his skills with reservation. That takes maturity, and to find that in a four-year-old truly boggles the mind.
Update: He's actually six years old now (and five in the video below). But, whatever:
