The concert begins at 8 p.m. and will air on PBS.
Since being named the "Idol" winner Thursday, Glover has been busy with TV appearances and interviews.
The night after winning, Glover was a guest on "The Tonight Show With Jay Leno." She told Leno that while she is excited she won "Idol," she is also happy the show is over.
"I'm definitely glad that I don't have to sing every Wednesday and have to worry about being cut the next day or the stress and everything," Glover said. "But I'm glad I won, as well."
On Monday morning, Glover was a guest on "Live! With Kelly and Michael." She talked about auditioning for "Idol" a third time and what had changed.
"I think I turned myself more into an artist than a singer, so that had a lot to do with it," Glover said.
On Monday night, she was on "106 and Park" on BET. Glover talked about meeting her music idol, R&B artist Drake. After performing his song "Find Your Love" in the Top 4 on "Idol," he surprised her during that week's results show and gave her some career advice backstage.
"He said he could tell I was letting the stress get to me," Glover said.
Drake's advice: Have fun and be yourself.
Glover's "Idol" coronation song and first single, "I Am Beautiful," can be downloaded on iTunes, where it debuted at No. 9. Her album, "Music Speaks," is expected to be released July 16 and is available for pre-order on iTunes. She'll tour with the rest of the Top 10 "Idol" contestants this summer and will perform in Charleston on Aug. 5.
