Watch the acoustic version of the "X Factor" champs' debut single.

Before the U.S. version of "The X Factor" was placed on permanent hiatus, the singing competition discovered the lovely pop-rock duo Alex & Sierra, who became the first group to win a season of the show last year. Alex & Sierra's first single, "Scarecrow," hit digital retailers on Monday (June 23), and you can hear an acoustic take on the song exclusively at Billboard.com:

Alex & Sierra became known for covers of songs like A Great Big World's "Say Something" and Sara Bareilles' "Gravity" on their quest to win Season 3 of "The X Factor." "Scarecrow" demonstrates the duo's original songwriting, and the acoustic version displays the power of their harmonies in a stripped-down arrangement.

"'Scarecrow' is a song about hope," says the group in a statement. "It's about believing in a relationship so strongly that a lack of communication isn't enough for you to give up on the other person. Everyone has trouble communicating sometimes... Or all the time, and everyone deserves to be believed in. We are super proud that our first single is something we wrote, and we're super happy that it's something fun to listen to and fun to play."

Alex & Sierra performed "Scarecrow" on NBC's "TODAY" on Monday, and the duo's debut album is due out later this year. Listen to the studio version of "Scarecrow" below:
