Billie Eilish revealed that she’s recorded a new album in lockdown during an interview with Stephen Colbert on “The Late Show” Tuesday night. It’s the result of her first prolonged period of not touring since her career began in earnest in 2016.

“I don’t think I would’ve made the same album, or even the album at all, if it weren’t for Covid,” she tells Colbert. “That doesn’t mean it’s about Covid at all, it’s just that, when things are different in your life, you’re different. That’s just how it is. So, I have to thank Covid for that, and that’s about it.”

The logistics of recording an album may be easier for Eilish and her brother and musical collaborator Finneas, as they famously recorded most of their previous releases, 2019’s “When We All Fall Asleep, Where Do We Go?” and the “Don’t Smile at Me” EP, in the Los Angeles home they grew up in.

Eilish kept details about the album light, although Colbert asked her later in the interview if she showed off her vocal chops on the new material. “There’s a couple of moments on this album where I pull some tricks out. It’s really just about what I feel like sounds good.”

She has released four new songs in the nearly two years since “When We All Fall Asleep” dropped: “All I Ever Wanted”; the title theme from the delayed James Bond film “No Time to Die”; “My Future” and a recent duet with Spanish singer Rosalia, “Lo Vas Olvidar.”

Eilish also talked about the imminent release of her documentary, “The World’s a Little Blurry,” which captures her hectic life in the months leading up to last year’s Grammy Awards, which saw her and Finneas capturing multiple awards, including Best Album, Song, Record, New Artist and Producer, among others.

While the cameras were omnipresent during her tour — as noted by Variety in our 2019 cover story on the singer — she says, “I think it’s important to know, though, as an audience member of a doc, it’s not everything. You’re seeing a sliver of my life at that time.”
