Carrie Underwood's 'Two Black Cadillacs' lyrics come from a dark place -- something the singer-songwriter seems to manage well.

Some of her biggest hits to date include her windy chart-topper 'Blown Away,' as well as the revenge-filled hit 'Before He Cheats.' So when it came time to write the next big hit in 'Two Black Cadillacs,' Underwood already knew the general direction she wished to take the tune, which she knocked out with Josh Kear and Hillary Lindsey.

"It was the first time that the three of us had written a song together," Kear tells Taste of Country. "I had written with both Carrie and Hillary separately, but never in this particular combination. You assume that it's going to work, but you never truly know."

"Carrie had told me in an earlier writing appointment that she was expecting this album to have darker tones than any of her earlier records," Kear continues. "So I remember sitting at the piano while writing the song thinking that if Carrie really wanted something dark, this was what she was after."

"Two black Cadillacs driving in a slow parade / Headlights shining bright in the middle of the day / One for his wife / The other for the woman who loved him at night... Two months ago his wife called the number on his phone / Turns out he been lying to both of them for oh so long / They decided then he'd never get away with doing this to them / Two black Cadillacs waiting for the right time, right time," the trio wrote in the 'Two Black Cadillacs' lyrics.

"Carrie really got into the story and making sure we didn't give away how the two women got rid of the man the song is about," Kear recalls. "This kind of song is really tricky because you need enough detail to tell the story and keep it interesting without it becoming so graphic that it's unpleasant to listen to more than once."

"And the preacher said he was a good man / And his brother said he was a good friend / But the women in the two black veils didn't bother to cry / Bye, bye / Yeah they took turns laying a rose down / Threw a handful of dirt into the deep ground / He's not the only one who had a secret to hide / Bye bye, bye bye, bye bye," they wrote in the song's haunting chorus.

"I think we managed to pull that off," Kear notes of the lyrics. "Either way, it was certainly fun choosing which elements of the story to put in and which ones to leave out."
