I have to admit that I am not a huge fan of the stomping swaying.  But my wife and children (especially our oldest, who started orchestra in school this year) are huge fans of Lindsey Stirling, the dubstep playing dancy-pants violinist.  She certainly wins big nerd points with her gaming and movie covers (video’s below), including Mission Impossible, Zelda, Skyrim, Halo, and Star Wars.  I like the silent violin Lindsey plays in the Mission Impossible cover.  Lindsey can be found on YouTube at lindseystomp.
