Finneas O’Connell says Billie Eilish has taken on more of her own vocal engineering across the three albums they have made together, a shift that has made her workflow faster and changed the way he approaches production. He said he has been teaching her more of the technical side over time, and that she now has the kind of ear that can shorten a session by seconds every time she reaches for a sound.
The comment lands now because Finneas is in a period of visible creative widening. Known first as Billie Eilish’s producer, he has also worked with Justin Bieber, Halsey, Kid Cudi and Ashe, released two solo albums, and put out For Cryin’ Out Loud! in 2024 and The Dream in 2025. In On the Record, he talked about how the role of a producer has changed as recording has become cheaper and more accessible, and he said his own process has evolved over the last decade.
That evolution runs through the way he describes Billie Eilish in the studio. Finneas said that when she gives him a metaphoric direction, such as wanting a vocal to sound like it is falling apart, he can interpret it and chase that exact feeling in the mix. He said that is part of what he loves about producing: the back-and-forth where the artist brings the image and he translates it into sound. He also framed the artist as a second director, a reminder that the job is no longer just about pressing record and shaping levels after the fact.
But Finneas also put his finger on the friction inside that ideal. He said he wants an artist to be purely imaginative, while also warning that the more technical detail someone knows, the less freely they may imagine. In his telling, Billie Eilish’s growing knowledge makes her faster, but it also moves her closer to the machinery of the job he once kept to himself. That is the tradeoff inside modern pop production: more control, more speed, and less mystery.
Finneas has been using that same approach beyond the studio, applying his skills to craft the score for the newest season of Beef. The project fits the version of him that now moves easily between songs, scoring and collaboration, but his comments about Billie Eilish show the core of his work has not changed. He still wants the singer in front of him to imagine the impossible. He just now has to build the sound with someone who understands more of how the trick is done.
