"Between Raising Hell and Amazing Grace," released in June, is the pair's third album, and follows 2005's "Comin' to Your City."

The duo recently celebrated its first No. 1 hit, with the lead single from the new album, "Lost in This Moment," climbing to the top of Billboard's Country Singles chart.

Penned by Rich along with Rodney Clawson and Keith Anderson, the song had sat on the duo's shelf for several years. "It's been sitting around in a catalog for four, five years now," Rich recently told CMT Radio. "Just didn't seem like, early on, something we would sound good doing. But we listened to it on the bus and I said I always thought this was a pretty good song ... we said let's cut it and see how it turns out. And it turned out really great."
