Showalter had an impressive July 25 performance competing against talented solo singers, duets, and groups of all ages — all in the running for the $1 million grand prize.
She is now headed to the final round after wowing the crowd with her rendition of "Before He Cheats" by Carrie underwood.
Catch her compete on local NBC at 8 p.m. Thursday.
A 1992 DSU graduate with a Music Education degree, Showalter has been promoting her strong Delta connection since gaining recognition on the show.
Dr. Kimberley Broadwater, a former DSU classmate of Showalter, has been passionately rooting for her old friend.
"I think it's great that she hasn't forgotten her Delta roots," said Broadwater, who once taught in DSU's music department, before making the move to Mississippi Valley State University. "Since the minute she found out she'd be on the show she's been reconnecting with all of us.
"Every statement she's made on the show has been about back home and being proud to be from Mississippi."
Born in Columbus, Showalter spent her youth in Louisville. She graduated from Greenwood High School before attending DSU.
At Delta State, Showalter earned her title as Miss Delta State in 1991 and went on to participate in the Miss Mississippi Pageant where she was named a talent winner and second alternate.
She currently resides in California where she has taught performing arts for over 10 years.
"I'm so proud of Amy," added Broadwater. "She's living her dream performing and teaching. I think it's awesome what she's already achieved."
Dr. Mary Lenn Buchanan, a voice instructor at DSU, is also proud of Showalter's dedication to the green and white. She remembers her as a very strong student in her classes.
"I think it's thrilling — number one because she is doing so well for herself, and number two, she is promoting DSU as her alma mater," said Buchanan. "We're all very proud of her."
Barry Bays, a DSU music instructor and director of DMI bands, said he's excited to see a former student succeed on national TV.
"The music department was awesome at the time she was a student," said Bays. "Anyone who came through the program had to be good, and she's certainly showing that."
Showalter has thrived thus far after being judged by a special in-studio panel of 101 'music experts.’
Judges vote for the act they like best in each duel, with the unique twist that each competitor has the opportunity to negotiate a deal after they perform.
Competitors can "take the money and run" or choose to stay in the competition for the million. Viewers who play along online also have a chance to win $10,000.
Local supporters and friends are routing for her to reach the ultimate prize.
