15-Year-Old Pop Prodigy Billie Eilish Announces Debut EP & First-Ever Tour

No, really. Two years since her accidental hit “Ocean Eyes” went viral on Soundcloud, the 15-year-old Californian singer-songwriter and dancer is announcing an August 11 release for her debut EP,

-- lowercase, no apostrophe -- and dropping its latest single, “COPYCAT,” today (July 14). To add to the hype, the singer hits the road for her first North American tour in the fall.

hours after returning to Los Angeles from her sold-out, first headlining show in London, even Eilish can’t quite comprehend her own success. “When I had four songs out, there would be fan accounts, and they’d be like, ‘guys, what’s your favorite Billie song?’” the singer born Billie O'Connell recalls over the phone. “And I’m like, dude. There are

But that sense of disbelief starts to fade -- replaced by obvious understanding -- the moment you tune in to the singer’s drawling, Lorde-meets-Lana Del Rey vocals and simmering, dark pop sound. 

Take the new “COPYCAT,” a smoldering, hip-hop influenced track Eilish (pronounced

) wrote with her older brother and songwriting partner, Finneas, about her impatience for lack of originality -- among friend circles, the music industry and otherwise.

“I knew exactly what I wanted to write about. It’s really cliché of this to happen, because yeah, as you get more recognized and [are] more of a big deal, then people start copying everything you do,” she explains. “But if you’re going to do everything I do, what’s the point of even trying to be you, if you’re not even you at all?”

Though the song's trap-like feel stems from Eilish's interest in hip-hop, particularly XXXTentacion and Tyler, the Creator, its signature grungy bassline was Finneas' invention.

“He played this weird, creepy bass sound, and I thought it was so cool.” She makes a guttural

noise through her teeth. “You know?” It’s the sighing piano bridge that gets people, though, when after a weepy, sugar-sweet apology, Eilish turns on the listener with a cruel whisper:

To fans of Eilish’s previous work, the track’s darker vibe shouldn’t come as a surprise. She turned heads -- and raised eyebrows -- at 14 with the single “Six Feet Under,” and in the more recent “Bellyache,” she takes on the persona of a conflicted serial killer. (At first listen, fans may well have interpreted “COPYCAT” as a reference to the 1995 horror flick.)

“[People] feel like you have to write about what you’re going through, and how you feel, and it can’t be anything else -- and that’s just so untrue,” Eilish says of her music’s unusual characters. “You don’t have to be in love to write a song about being in love. You don’t have to hate someone to write a song about hate. Writing music is just like writing a book.”

Trust Billie -- despite her tender age, she's been doing this quite a while. The homeschooled daughter of two actor and musician parents, Eilish began singing in the Los Angeles Children’s Chorus at 8 years old.

In fact, Eilish and Finneas have “like, a million” songs in their unreleased arsenal that take on a range of personas, from the perspective of a boy Eilish “broke the heart” of to the fictional

character Nancy. “It can make you more forgiving in a way, because it’s like, ‘wow, maybe I should put myself in their shoes,’” she explains.

will follow a distinct plot. The only tie-together? “I’m pretty sure I don’t have any songs that are about how much I love someone,” she says, laughing. “They’re all either about like, ‘I hate you,’ or ‘you make me hate me.’”

As for the EP's intimidating title, anyone who follows Eilish on Instagram is aware that the singer

 to smile in photos -- "I have an ugly little tooth," she jokes. But like most things Billie Eilish, it goes deeper than that. "I like to be in control of how I look and how I feel and how I act and the obligation is to smile back at someone if they smile at you," she writes

 later over email. "Therefore, DON’T SMILE AT ME."

And even as the hype surrounding her name (and youth) continues to build, Eilish says she feels little anxiety over living up to expectations with her EP. In fact, it’s still settling in for Eilish that she has listeners at all.

“It’s really weird,” Eilish says, at a loss for words for the first time during our call. “Because I don’t think of myself as anything, except me.”​
