The last woman standing on Team Blake, Dia Frampton, took the stage beside Blake Shelton himself on tonight's final performance episode of 'The Voice' to perform a rockin' rendition of Tom Petty's timeless 1989 hit, 'I Won't Back Down.'

"It's the perfect song to sing on this last show," Frampton said backstage as she rehearsed her pick for her last night performing on the NBC show. "'I'll stand my ground' is the perfect last lyric I'd want to finish on.'"

We agree, and we think Frampton left a lasting impression with her delivery. When the duo took the stage, they weren't messing around. Frampton and Shelton rocked the arena side by side, both sporting black suits and sunglasses a la 'Men in Black' or the Blues Brothers. Of course, the ensemble wasn't complete without electric guitars for each of them and a full backing band, also wearing black suits and ties.

Frampton didn't seem to feel a single nerve in her body as she strummed her guitar and spit that raspy voice into the mic. Shelton offered a perfect complement, but overall, he let the aspiring singer take her moment. When he did get a line to sing, the crowd erupted in loud cheering, happy to see the favorite coach doing his thing.

Though, when they weren't screaming, the whole audience was singing along to the Petty classic. 'The Voice' finale airs on NBC tomorrow, June 29, at 9PM ET.
