In their first interview since announcing their split on Monday, country music duo Brooks & Dunn explain why they’re breaking up after close to two decades of performing together.

Kix Brooks and Ronnie Dunn say they’re out of ideas.

“We feel good about it, though, I mean honestly, we both feel like it’s just too good of a horse to ride it into the ground, so that’s kinda it,” Brooks says in an interview that will air on CMT Insider this Saturday, August 15.

“I think we realized this may be it, but if it is, the one thing that we will always have in common is how much we appreciate our fans and what they have given us, not just the lifestyle but the 20 years of going on stage … so we just immediately went into how do we wrap this thing up? What’s the classy, right way for us to do this? And that’s what we’re focusing on now,” he continues.”

Brooks will join Dunn in releasing a greatest hits compilation, #1 … And Then Some, on September 8. The award-winning duo will also embark on a farewell tour, “The Last Rodeo Tour,” next year.

“We came to this decision that maybe it’s a good time to hang up the spurs, but before we do it, we’re gonna go ride the trail one more time. I’ve said this before, but we really feel that the one thing we’ll always have in common is how much we appreciate our fans and what they’ve meant to us over the years. So we’re really looking forward [to the tour].”
