Billie Eilish, Finneas Drop Acoustic Live Version Of 'Your Power'

Billie Eilish on Sunday shared an acoustic live version of her song, "Your Power," on Instagram, featuring her brother Finneas.

The 19-year-old singer posted the powerful performance from her upcoming music album, "Happier Than Ever," which is slated for release on July 30.

In the video, Eilish and her 23-year-old brother can be seen sitting side-by-side on two stools in a minimalist room, surrounded by brown curtains and a chandelier. The video begins by slowly zooming in on the pair performing, and then stops at Eilish.

Fans praised the singer for her performance in the comments section. One of the fans wrote, "YOUR VOICE COMES FROM HEAVEN," while another fan wrote, "Billie hasn’t changed.. she’s better than ever! Sexy af."

The full version of the song was released on YouTube the same day. The clip was directed by Kyle Goldberg and edited by Austin Prahl. The beautiful set was designed by Keith Wright, Dominique Falcone, and Sydney Emery.

The music track, "Your Power," was originally dropped in April.

At that time, the singer noted "Your Power" is one of her favorite songs she has "ever written."

"I feel very vulnerable putting this one out because i hold it so close to my heart," she wrote on her Instagram. "This is about many different situations that we’ve all either witnessed or experienced. i hope this can inspire change. try not to abuse your power."

The singer has often been spotted wearing oversized clothes. However, after the music track was released in April, she posed for a lingerie range in May and appeared on Vogue's cover.

"I saw a picture of me on the cover of Vogue [from] a couple of years ago with big, huge oversize clothes [next to the new Vogue cover]. Then the caption was like, ‘That’s called growth’," she told Rolling Stone in June. "I understand where they’re coming from, but at the same time, I’m like, ‘No, that’s not OK. I’m not this now, and I didn’t need to grow from that.’"

Besides music, the singer also released a documentary based on her life, "Billie Eilish: The World’s a Little Blurry" on Apple TV+ in February. Eilish will also feature in a new documentary titled "What Do You Want from Me?"
