The biggest response from the crowd came during Underwood's thunderous performance of her woman-scorned anthem, "Before He Cheats."
Underwood also endeared herself by dedicating a brief verse from "Country Roads" to her West Virginian fans.
Hayes returned to the stage for a duet "Leave Love Alone" and the wonders of modern technology allowed Underwood to sing "Remind Me" with a digital image of West Virginia native Brad Paisley.
The Paisley video was just one of many high-tech spectacles of Underwood's stage production, which also included large LED screens, a simulated cyclone erupting from the stage floor and an imitation hot air balloon lifting the singer above her astounded and adoring audience.
The encores of "I Know You Won't" and the popular title track from her new album, "Blown Away," were also highlights. The concert's tornado imagery was a fitting metaphor for the whirlwind of wail that is Underwood.
Rarely has a singer proven to be such a force of nature in concert, pushing their voice to its very limits with every note of every song. Underwood's live performance was fierce, fantastically flamboyant and filled with nonstop energy.
