Crowned Vocal Duo of the Year at the Academy of Country Music Awards in both 2012 and 2013, Thompson Square’s mix of country, pop and classic rock has earned them broad popularity.

Performing at a “Nashville Nights” show at the Hyatt Regency Maui Resort and Spa on June 28, the husband and wife duo of Keifer and Shawna Thompson most recently released the single “Make America Great Again,” joined by fellow country artists Gretchen Wilson, John Rich and Jerrod Niemann. A video for the song opened with a clip of Donald Trump declaring “together we will make America great again.”

The multi-platinum-selling duo grew up with a passion for country.

“Everything was rooted in traditional country music,” Keifer Thompson explained. “For me it was (Merle) Haggard, Elvis, Roger Miller, George Jones and Waylon Jennings — all the greats. As I got older, I discovered rock ‘n’ roll and fell in love with it. My influences are country and rock with a pop flair. Shawna grew up on stone-cold country, too, Reba (McEntire), Pam Tillis and Patty Loveless. She knows her way around old-school country music.”

The two musicians met the first week they had both moved to Nashville at a songwriting competition. It was love at first sight. They tried pursuing solo careers, but after a few years, they decided to pair up and formed Thompson Square with Shawna singing vocals and Keifer playing guitar and singing vocals.

“We started dating for three years, and then we were married for three years doing our individual things,” he recalled. “Then we decided we wanted to be together with music as well, so that’s why we joined forces and became Thompson Square. That’s when everything started happening for us.”

Choosing a band name was tough.

“It was one of the hardest things,” he said. “There’s two of us so it actually started out Squared and at some point we dropped the d.”

Were there other names that didn’t quite work?

“We were Runaway Gypsy for a while,” he revealed. “There were a whole slew of names. It’s the hardest thing to name your band.”

In the summer of 2010, the duo released their single, “Are You Going to Kiss Me or Not.” It became the Thompsons’ first No. 1 hit, sold double-platinum and became iTunes Country Song of the Year.

“It’s an unreal feeling because I had never had a dream come true,” he said of their success. “You have all this hunger and drive to get there and once you get there, you have to reevaluate what you’re doing and your goals. You just set more goals.”

More hits for the band followed with the upbeat love song, “I Got You,” from the self-titled debut album. For the accompanying video, the pair dressed up like pop legends Sonny & Cher. Their own song had reminded them of Sonny & Cher’s classic and they thought it would be fun to spoof the duo’s TV variety show.

“That was the most fun we’ve ever had with a video, and it actually won an award,” he said. “It was a brilliant video.”

A year after the album’s release, they were recognized as the Vocal Duo of the Year at the 2012 Academy of Country Music Awards and the Country Music Association Awards.

Thompson Square’s fifth single, “If I Didn’t Have You,” reached No. 1 on the Country Airplay chart in May 2013. It served as the lead single to their second album, “Just Feels Good.” A USA Today review praised how the “songs play like a rom-com with dual narrators. They’ve got all the elements — meet-cutes, separation, obstacles and a happy ending — plus a soundtrack that mixes ’70s- rock guitar with mandolin and pedal steel.”

Known as T2 to their fans, success continued with hits like “Everything I Shouldn’t Be Thinking About,” which became their fourth Top 10 hit. And in 2013, the duo again won Vocal Duo of the Year at the 2013 Academy of Country Music Awards.

With hints of Lynyrd Skynyrd’s Southern rock, the duo released the turbo-charged single “Trans Am” in 2015. Celebrating the iconic American car, this rocking, guitar-fueled song reflects their energetic, more up-tempo live shows.

Reviewing their latest album “Masterpiece,” Sounds Like Nashville praised, “their entire album spans a multitude of emotions and genres that keeps the listener intrigued.”

In between their own albums, the duo has contributed to “Working Man’s Poet: A Tribute to Merle Haggard,” which featured a collection of contemporary country artists singing the icon’s songs. And they appeared on Blues Traveler’s album, “Blow up the Moon,” co-writing the songs “Matador” and “I Can Still Feel You.”

Thompson Square will play a “Nashville Nights” show at the Hyatt Regency Maui Resort and Spa at 7 p.m. June 28. Tickets are $75 and $55 for Lahaina residents at Bit.ly/4llHBuD.
