Only on the "CBS This Morning" podcast, CBS News correspondent Jamie Wax talks with electric violinist, singer and dancer Lindsey Stirling about her Wanderland tour and holiday album, "Warmer in the Winter: Deluxe Edition." Stirling is a a two-time Billboard Award winner who grew her fanbase after reaching the quarter finals of "America's Got Talent" and later went on to place second on "Dancing With the Stars." She tells Jamie why not winning these competitions was key for her later success and why she wouldn't have a career if it weren't for the internet.
