Lindsey Stirling!
There is a good chance that I won’t be able to make JCCC5, but I REALLY think SeaMonkeys would love her. Seriously, if you haven’t heard of her, look her up. An absolutely amazing violin player, who I’m guessing is rather a nerd herself, based on some of the covers she’s done. (Zelda, LotR, Skyrim, Halo, etc)
