The rock and metal worlds have been acquainted with Halestorm vocalist Lzzy Hale for quite some time, but the rest of the music world is just getting familiar with her powerhouse vocals thanks to a pair of recent collaborations with electric violinist Lindsey Stirling and country superstar Eric Church.

Hale reached a wider audience this week, performing on national television with both acts. She teamed up with Church to perform 'That's Damn Rock and Roll' at the CMA Fest which aired on ABC, while she joined Stirling on NBC's 'America's Got Talent' to perform 'Shatter Me.'

Hale and Church will have a chance to recreate 'That's Damn Rock and Roll' on the concert stage more frequently this fall as Halestorm will join Church on the road. Their performance at the CMA Fest, which can be seen above, found the pair belting the poignant song, which while gaining steam in the country genre, definitely has some roots in rock as well.

Meanwhile, Hale joined Stirling on a homecoming of sorts, as Stirling got her first taste of fame as a competitor on 'America's Got Talent' several years ago. Though she didn't win, Stirling utilized the platform as a springboard for her career, becoming an Internet sensation, touring the world and releasing a pair of albums since.

The 'America's Got Talent' performance, which can be seen below, finds Hale performing at the front of the stage, while Stirling plays in mid-air before being lowered and grabbing the spotlight with her nimble fiddling.
