A capella country group Home Free continue to rack up the views with their fan-focused videos on YouTube. Their latest, a mash-up between Nitty Gritty Dirt Band's "Fishin’ in the Dark" and Little Big Town's "Boondocks," has helped the group garner more than 40 million views on YouTube, with no signs of slowing down anytime soon.

“When we started brainstorming about what songs evoke the spirit we want to convey on our new album, we thought, what are some of country’s biggest hits? Why not ‘Fishin’ In The Dark’ with something more recent? Little Big Town’s ‘Boondocks’! You wouldn’t think the styles would really mesh, but they do,” band member Austin Brown says  in a statement. “We messed around with them for a few weeks and they’re great together. The video is a blast too! We can’t wait for everyone to check it out!”

The video shows both thematic and vintage-looking graphics to make the song visually appealing as well. It's part of the group's plan to gain fans not only through their unique sound, but also through their attention-getting videos.

"It’s such a massive platform to be able to showcase what Home Free is all about," band member Austin Brown tells Roughstock. "We may have gained a lot of attention from being on and winning The Sing-Off but YouTube has been the single biggest part of our success in reaching the audience and giving them something to follow and enjoy."

Their latest collaboration is from their upcoming Country Evolution album, which also includes a duet with the Oak Ridge Boys on their 1981 hit, "Elvira."

“This is a pivotal year for Home Free,” bass singer Tim Foust says. “We’re coming into Country Evolution fresh on the heels of our Grand Ole Opry debut. We’ve gotten to collaborate with music icons such as the Oak Ridge Boys and Charlie Daniels. We’re excited to say the least.”

Country Evolution will be released on Sept. 18. It is currently available for pre-order on iTunes and Amazon.
