Atlanta-based indie-alt-folk group von Grey has checked off more things on the proverbial band wish list in the past year than many bands do in a decade. National TV? Check. They've appeared on "Late Show with David Letterman," "Conan," NBC's "Rock Center with Brian Williams," and CNN's "Road Warriors." Glowing press? Check. The harmony-laced foursome has been called everything from an "Americana masterpiece" to simply "crazy-talented" by the media. Great tours? Check. The group has opened for Indigo Girls, Sarah McLachlan, Lindsey Stirling, Rusted Root, and Company of Thieves, and performed standout sets at SXSW, Bonnaroo Music & Arts Festival, and Gathering of the Vibes Festival. Top 10 record? They can check that off too, as their 2012 self-titled EP shot into the iTunes Top 10 following their memorable "Conan" performance. And, the group of four classically trained sisters has accomplished all of this without the help of a record label and before their 20th birthdays.
