Nash sat down with Billboard backstage at Lolla to discuss the upcoming projects, as well as the recently released music video for her song “She Rules,” which was shot using an iPhone. Watch the full interview below.

“In this interim period while I’m writing my next record, and I’m working on a musical, and there’s pressure on thinking about an album and what I’m going to do next with my career, it’s fun to just release things,” Nash says of “She Rules.” “I wrote this song about my sisters and my friends, about all the girls I really love and appreciate.”

She explained how the video was shot using an iPhone. “I shot some stuff on my iPhone, then I sent my friends the beats without the rest of the song and got them to film themselves on the 8mm app just dancing, and then I edited it together on iMovie and released it a few weeks ago. It’s fun and about girl love,” she says.

Nash also discussed the forthcoming musical “Only Girls,” which features her music. “[Blankenbuehler is] using all of my music and writing songs to fill gaps in the story,” the singer says, noting that she’ll see a workshop in October. “So i’m writing a lot for the musical right now. that’s my main focus.”

But she’s also writing songs for her fourth album. “It’s my fourth album and I got dropped two years ago, then I worked to put out my record independently,” she says. “I worked harder than ever and learned so much, and made the record I’m most proud of. I feel like I’m at this point, like, ‘What am I going to do next?’ — in a business sense and also sonically and visually.”
