I asked him what he was doing and he said that the books set up around him are the cheering crowd and he was playing the drums in a concert for them. It was cute to watch, he had some of the auto music playing while he pretended to drum. He has loved the drums since he was 1 yr old and has even had a cople small drum sets but I think it's time for a bigger set. His inspiration for this came from a you tube video my husband showed Mr. E of a drum solo at a Rush concert.
