Season 12 American Idol runner-up Kree Harrison has announced that her debut album will be available this summer.

The project, titled This Old Thing, features 13 new tracks, nine of which Harrison co-wrote. The young country singer has been working on this record for the past two years, since the conclusion of her run on American Idol.

"I literally have never worked so hard in my life," Harrison tells People. "Idol taught me a work ethic like no other will."

The new album mixes her Texas-roots with her Nashville state of mind. She admits that her recent years in Music City served as heavy inspiration for her sound.

"My dad and mom listened to things from Otis Redding to old classic country," Harrison says. "I'm thankful that they showed me that from the get-go. But moving here, one of my best friends, John Osborne [of Brothers Osborne] showed me Darrell Scott. I would've probably never known artists like that if it weren't for the Nashville community. My music has definitely been inspired 100 percent by Nashville and the people here."

Also featured on This Old Thing is a song that Harrison co-wrote that hits very close to home for the singer — a personal track about the loss of her mother.

"I've always wanted to record it," Harrison says. "It's special to me and I think that it's good to put stuff out there, even if it's uncomfortable at times, because people can relate, and it feels good to be selfless with artistry."

The first single, which shares a name with the album, is available now. This Old Thing is slated for release on July 8. It's currently available for pre-order at iTunes.
