Kirstie Maldonado has gone country…

The 23-year-old half-Mexican, part Spanish-American singer and her fellow Pentatonix members took the stage at the Country Music Association Awards on Wednesday to present the CMA Award for Vocal Group of the Year.

But before revealing the winning group’s name, the a capella group honor a past winner of the award with a special performance of their song.

“As a vocal group ourselves, we wanted to salute a great country group that won this next award back in 1978 and this year entered the Country Music Hall of Fame,” intro’s Pentatonix frontman Scott Hoying, before Pentatonix launched into an a capella version of “Elvira,” the 1981 hit by the Oak Ridge Boys.

Proving Maldonado and her group mates are the real deal, the performance featured on point harmonies, including Avi Kaplan’s perfect bass part.

Audience members bobbed along and gave the group a standing ovation after the short performance.
