The Band Perry is definitely an unusual group of musicians.

While the world is full of musical sibling groups past and present, many of which achieved international success -- the Andrew Sisters,the Jackson 5, the Osmond Brothers and beyond -- this trio seems to truly have amicable relationships, something which many past familial groups have struggled to maintain.

"Our mother [Marie Perry] is our good luck charm," said Kimberly Perry with a laugh. "She's our good luck charm and our referee! We know each other like the back of our hands. And when there are fireworks, she helps us take a step back until things cool off."

Of course, the trio's career remains red-hot. Kimberly, Reid and Neil Perry broke out with the 2011 quadruple-platinum single "If I Die Young." The No. 1 tune and CMA Single and Song of the Year was just the beginning of the success sparked by the group's self-titled debut album. The songs "You Lie" and "All Your Life" also became hits.

Now Kimberly, Reid and Neil Perry are on tour behind their sophomore album, "Pioneer." The multiple-award-winning band used the album to build on its brand of country rock.

"When we set out to record 'Pioneer,' the three of us drove across the country from Greeneville, [Tenn.], to Malibu, [Calif.], to work with one of our musical superheroes, Rick Rubin," said Reid Perry. "Our time in the studio with Rick was so incredible because during our early sessions, he challenged us to set higher goals as songwriters."

After those sessions, the Perry siblings took the music back to Tennessee and worked with Dann Huff on production. The combination of creative talents appears to have conjured up future gold for the group.

The lead single from "Pioneer," "Better Dig Two," topped the Billboard Country Chart this week and marked the group's third No. 1 at country radio. The song is the fastest rising of their career.

"We have always been attracted to tight family harmonies," said Kimberly. "We know each other so well and work so well creatively, we take our distinct personalities and ideas and blend them into our own sound."
