Haim have dropped a brand new song, 'Lost Track' - watch

Haim have dropped their brand new song, 'Lost Track'.

Announced yesterday, it's the song the band previewed ahead of recent screenings of the Alana-starring Paul Thomas Anderson film Licorice Pizza.

You can check it out below.

Announcing the news on social media, the band wrote: ""I’ll never get back what I lost track of”

"We had that line written for the last year but could never figure out what to do with it. We kept writing it down, not knowing where it should live.

"Cut to PTA [frequent collaborator Paul Thomas Anderson) shooting the director’s cut issue for W Magazine with our baby sister on the cover! An opportunity arose to do a quick music component while shooting the story. Paul mentioned having the book “Appointment in Samarra” as a possible direction. So we did some digging around the book and were inspired by the scene where the main character throws a drink in someone’s face at a country club. We were inspired by the idea of someone doing something so drastic to get out of a situation they felt uncomfortable in - just to feel something.

"We finally remembered that lyric and wrote and recorded the song and shot the whole thing in a few days! Anyway, felt fun to do something very collaborative/ off the cuff."
