Shania Twain is preparing to come back with her first new album in 15 years, teasing a less poppy sound and darker material that deals with the end of her marriage to producer Mutt Lange in 2010.

"It needed to be really pure and my own story and my own emotional journey," she tells Rolling Stone of her new material. "I was now alone all of a sudden, and I didn't want to shy away from it. And that's not a collaborative thing; it's a very personal thing."

During the hiatus between albums, Twain has dealt with a vocal-cord disorder she believes was caused by stress, with her marital troubles being a contributing factor.

Twain and Lange, who produced her hit albums including "Come On Over," ended their marriage when she discovered he was in love with their longtime friend Marie-Anne Thiébaud. The turmoil became even greater tabloid fodder when Twain went on to marry Thiébaud's ex Frederic in 2011. 

She's open about how this inspired her new music. The song "Who's Gonna Be Your Girl" is about "feeling unappreciated and knowing that you are secondary," she says. "Having to live with someone that has different priorities and accepting that you're not the most important thing in a person's life." 

Twain plans to release the yet-to-be-titled album in May, with a single coming in March. She says she told anyone she was working with to forget about her previous sound with Mutt. 

Ultimately, she says the process of "reflecting on the darkness" helped her personally.

"It helped me come to terms with a lot of things emotionally," she says. "It's sort of like when you finish crying. When you're done, you're done and you move on."
