Staying with a urban/hip-hop/musical theme.
This guy goes by the name KENTARO. He is a former world champion at "DMC" disco mix championship. Each dj gets 6 mins to show off their skills.
I have been going to see the finals for the past 10 years, and I have never been blown away with the abilities these guys have until I saw Kentaro.
