Internet sensation and billboard topper Lindsey Stirling was the focus of "Song by Song," a documentary music series which premiered on Ovation TV Tuesday, Dec. 9. The first part of the two-part episode featured her song “Crystallize” while an episode on Dec. 16 will focus on another chart-topper: “Elements.” Known as an electronic violinist, dancer and composer, the Gilbert, Arizona, native first rose to popularity after her appearance on the incredibly popular "America’s Got Talent" in 2010. Though she did not win the competition, the exposure helped her to become a YouTube sensation in 2012, when her song “Crystallize” became one of the top 10 most-watched videos of the year, with more than 42 million views and more than 5.5 million subscribers. The series takes an in-depth look at two of Stirling's biggest hits, with behind-the-scenes insights from renowned choreographer Laurianne Gibson; the Grammy-winning lead singer of Halestrom, Lzzy Hale; and singer-songwriter Dia Frampton, as well as "Billboard's" Andrew Hampp, "Rolling Stone's" David Wild and YouTube's Margaret Hart. Viewers will also hear intimate, behind-the-scenes stories from Stirling and her sister Brooke, as well as her drummer Drew Steen, keyboardist Jason Gaviati and tour manager Erich Jackson.
