Trying to make it in the music business may not be for the faint of heart, but for Angie Johnson, it's a piece of cake compared to the former Air National Guard staff sergeant's earlier career.

Serving in the military "was like basic training for my life," says Angie, who also competed on "The Voice." "There have been so many people who think they are in stressful situations and I'm like 'Really? Should I be stressed out right now because this is nothing like Afghanistan. I'm not wearing Kevlar and I'm not wearing body armor, so I'm good'. That is the perspective I carry with me," she tells The Boot.

The Sony Music Nashville artist will release her Josh Leo-produced EP on May 21. "I'm really proud of the project," Angie says, especially of the title track, "Sing For You," which she wrote. "It's a tribute to my brothers-and sisters-in-arms," she says. "The rest of [the EP] is very reflective of who I am. It's a fun record."

Angie remains best known for her cover of Adele's "Rolling in the Deep." The video of Angie performing it with an Air National Guard Band went viral and has drawn more than 3 million page views on YouTube. While she may not get stressed out about making it on Music Row, the thought of meeting Adele is enough to make her quiver. "I'd be really shy if she ever came out and said that she'd seen [the video]," Angie says. And it's not just Adele's voice that she admires: "I just so love her personality. She's just so real and honest all the time. I've sat up for hours watching her YouTube interviews. She's hilarious. You just never know what she's going to say."
