I thought it was great, and I usually find drum solos to be rather dull. (I know that's a risky statement to make on a drum forum!) The thing is, there were probably many drummers competing who had chops galore. So, competitors must find ways to distinguish themselves beyond technical ability. That's exactly what this guy was doing. He had the chops for sure, but he also made an entertaining show of it and encouraged some audience participation. He also had great energy and enthusiasm, and smiling actually helps too! I thought the "Smooth Criminal" riff was great. I also liked his "running" style of playing. The one place where I thought it fell short was on a musical level. When I hear a drum solo, I like it to be more of a musical composition, almost like a song played on the drums, as opposed to a bag of tricks demonstrated one after the other. His composition definitely fell into the latter category. But somehow, it worked in this case. I think the overall fun nature of the performance really carried it through.
