Lindsey Stirling has hinbekommen here a very nice mix of electronic music and an old-fashioned classical violin. As criticism one could note that certain sections in other songs not be repeated too much changed, cynics would claim "recycled" but since I love these sections, I am glad if I can hear it in different, interesting new variations.
The only thing I am sorry that there are so few (electronically distorted) vocals, they fit really perfect in their music. Nice to hear in "Electric Daisy Violin". Where that would be just the icing on the cake, its pieces work without excellent and in some you certainly would even bother.
