McLain recently competed in the Colgate Country Music Showdown in Indianapolis and with eight others, advanced through the first round.
By doing so, he will now perform at the HH Gregg Country Music Expo, April 18-19, at the Indianapolis State Fairgrounds.
"It's going pretty well," McLain said.
The concert will take place in the Marsh Blue Ribbon Pavilion at the fairgrounds.
McLain said he will perform sometime between 11 a.m.-1 p.m. He will have 10 minutes of performance time and will sing, "One Star, One Stripe At A Time," which is currently available for purchase at www.paradiseinnovations.com.
The HH Gregg Country Music Expo will be presented by 95.5-FM WFMS, a country music radio station based in Indianapolis. This year, the annual event features artists Lee Ann Womack, Darius Rucker, Heidi Newfield, Blake Shelton, Mark Chesnutt, Jamie O'Neal, Jessica Harp (from The Wreckers), along with Jason Michael Carroll, The Lost Trailers, Little Big Town and Emerson Drive.
McLain will have his own booth set up at the event and will be selling merchandise.
In addition to his current song being available for purchase, McLain said there is a video performance of the song accessible at www.youtube.com.
McLain said he is still working on a full album, but currently, his single is the only available song.
He said he has not decided on the other song he will play.
However, he said it will be his own material.
In May, McLain will also attend the Applause Rising Talent Showcase (ARTS) in Chicago. At the event, he will have the opportunity to perform a 90-second clip of his original song, "No Wind For My Sail."
McLain will perform the clip in front of agents, casting directors, producers, managers and other industry executives.
McLain, 37, is a 1990 Turkey Run High School graduate and current Clay County resident.
He began writing his own material in 2000.
