The Rankin Twins are set to release a new EP in December, and they're sharing the video for one of the new tracks exclusively with readers of The Boot.

Amy and April Rankin are already well-known to country fans in their native Texas, where they have released several regional hits including 'Rain,' 'Holdin' Pattern' and 'Jezebel.' They've also received national exposure from their full-length debut, 'Moonshine and Maybes,' and became Top 3 finalists on NBC Universal/Cozi TV’s new reality series, 'Next Great Family Band.'

They're releasing a new EP titled 'Good Vibes' on Dec. 2, and recently filmed a video for one of the new songs, 'Never Yours to Break,' in Austin with director James Hill. The track and video feature a third voice in their trademark harmonies.

"'Never Yours to Break' is the first song and video for us to collaborate with another female artist, and it's one of our dear friends, Kimberly Kelly," Amy explains. "So, this was a really fun song for us to put on the EP."

It's just one of many musical flavors on the upcoming project.

"The 'Good Vibes' EP touches on all of the different aspects of a relationship," Amy adds. "Summer love to the stickiness of whether to stay or go and then the ultimate end all be all, I'm over you, anthem song. We basically walk you through our lives in relationships in one quick EP. "
