You know them as:
Rayna's (Connie Britton) daughters, Maddie and Daphne.
Why we like them:
In a show about established country artists and up-and-coming songwriters, their talent-show act manages to be the most compelling performance of all! Their arrangement of "Telescope," originally sung by Hayden Panettiere on the show, lit up Twitter as fans clamored for more of their work. Luckily, there's plenty of it -- the real-life sisters have been performing together for years, and their cover of Robyn's "Call Your Girlfriend" went viral on YouTube.
Where else you've seen them:
Nowhere! "Nashville" is the girls' big break, so unless you've caught them on YouTube, they're completely fresh faces.
