In a rare serious moment, Colton Swon talks about what it's like to finally break out in country music, with his big brother as his partner.

"We're just a couple of guys from Oklahoma, but we've been to five different countries and done things we never thought we'd be able to do," says Colton, 26, the younger of the Swon Brothers. "As much crap as we give each other; I get to do it with my best friend."

That would be Zach Swon, 29. The pair, known for their tight harmonies, rose to national attention during the summer of 2013 on NBC's "The Voice." Earlier this year, their single "Later On" hit No. 24 on the country charts. And in June, they made Country People's 50 Sexiest list.

The Swon Brothers, who will play a free show Tuesday in West Palm Beach, started out singing as children in their parents' gospel group, in Muskogee. Yes, they are Okies from Muskogee.

"We are country music fans through and through, and any band that had harmony — Diamond Rio, Lonestar, Little Texas — that's where we live," Zach says. "If we can take any of that and make it current. I think if the Eagles came out today, they'd be considered a country band."

When the Swon Brothers auditioned for "The Voice," three of the show's four judges elected to send the band through to the next round. They finished the competition in third place.

"Looking back, it's one of the things that's just really hard to believe," Colton says. "We haven't had a chance to watch it all. We sang with Bob Seger, for crying out loud. Not many people get to do that."

The brothers' boyish charm and good-natured attitude caught the attention of Country People, which named them among country's sexiest men.

Zach: "I don't if you know it, but it actually was supposed to be just me, and Colton actually photobombed the whole thing."

Colton: "He is the guy who just will nonchalantly have the magazine. He thinks it's a great icebreaker. He just carries the magazine around, just happens to have it."

Zach: "Page 58."

The brothers signed with Arista in 2013, though they have yet to release an album.

"When we started this thing, we just wanted a record deal," Zach says. "We thought that was the hard part. Now, we learn keeping the record deal is the hard part."

The Swon Brothers will perform 6 p.m. Tuesday, Aug. 19, at CityPlace, 700 S. Rosemary Ave., in West Palm Beach. Call 561-366-1000 or CityPlace.com.
