2Steel Girls Allison & Krystal Steel Nashville 2Steel Girls from NBC’s, The Voice are the only mother-daughter duo to appear on the show to date. And yes, you read that right, they’re mother and daughter. Personally mentored by country music superstar, Blake Shelton, Allison and Krystal appeared on three episodes of the show before breaking another major barrier: They became the first music artists to ever launch a debut, independent single with a live performance in front of millions of viewers on the Today Show all because of a fan initiated campaign. Now, how cool is that!?!?!? 2Steel Girls have opened for some awesome, music artists and headlined quite a few pretty cool shows on their own. They’ve also had the rare honor of playing shows with celebrity comedian, Larry the Cable Guy, and performances on the Hallmark Channel, RFD TV, Fox , etc. As Lydia Picknell (Keepin’ It Country) says, “Get to know the duo before they make it big – because they will. 2Steel Girls are rising stars!”
