Trump's inaugural committee announced that country stars Toby Keith and Lee Greenwood as well as Broadway singer Jennifer Holliday would perform at the Lincoln Memorial.
The event, during which Trump will speak, will be free to the public and take place on Thursday on the eve of the real estate tycoon's inauguration as the 45th president.
Keith, one of the most prominent country singers of the 1990s, after the September 11, 2001 attacks released the song, "Courtesy of the Red, White and Blue (The Angry American)," a passionate call to arms in Afghanistan.
Greenwood, 74, is a veteran country singer best known for his 1984 song "God Bless the USA," which has risen back in popularity at times of war.

"I'm honored to be part of history again and sing for President-elect Donald Trump. This is a time to overcome challenges in our country and band together," Greenwood, who performed at inaugurations of the last three Republican presidents, said in a statement.
Country music historically is most popular with white Americans, especially in the South, a stronghold of support for Trump who campaigned on a hard line against Mexican immigrants, Muslims and other minorities.
Holliday said she that been barraged with negative responses, including online threats, since the announcement.
"I was like, nobody knows that I'm alive and then I decide to sing a song and I wake up and they all hate me," the 56-year-old told music magazine Billboard.
Holliday said she voted for Trump's rival Hillary Clinton but believed it was important to provide "fair representation" at a presidential inauguration, rather than have exclusively white performers.
The inauguration lineup pales in comparison to the star power amassed by Obama.
A similar inauguration-eve concert at the Lincoln Memorial in 2009 drew Beyonce, Shakira, Bruce Springsteen, U2 and Stevie Wonder, as well as country superstar Garth Brooks.
Trump, despite a career spent in entertainment circles, struggled to find celebrity backers in his campaign against Clinton.
