WATCH: Home Free debuts their music video for 'Good Ol' Country Harmony'

Home Free is getting back to their roots!

The a capella group and winner of the fourth season of 'The Sing Off' exclusively debuted their new music video on AOL for their song, "Good Ol' Country Harmony', from their album, 'Country Evolution' -- and it's a toe-tapping good time.

In the video we go back... way back to high school where it all started. Austin Brown (high tenor), Tim Foust (bass), Rob Lundquist (tenor), Adam Rupp (vocal percussion/beatboxer) and Chris Rupp (baritone) all have a fun teen character in the video and it shares a little slice of their own history as several of the original members of the group met and performed together back in their teens.

The song's lyrics highlight some of the great country tunes and the bands behind them. "Won't you sing for me /Some good ol' country harmony /And let it ring Just like Alabama would always sing / The night is young and so are we / And there's just one thing that'll kick it off more perfectly / And that's some good ol' country harmony," the group croons.

Needless to say their vocal chops and range are pretty incredible. The group made their Grand Ole Opry debut in July 2015 and has been out on tour in Europe since January.
