Listen: Finneas' new song, 'I Lost A Friend'.

In the middle of his tour opening up for his sister Billie Eilish, Finneas has dropped a brand new single, ‘I Lost A Friend’ - a heartfelt song about a friendship falling apart, with Finneas realising, “I know I’ll be alright / But not tonight.”

About the song, he says: “This song was born out of a falling out I had with my childhood best friend. I’ve made a lot of music covering romantic relationships and a lot covering family but I’d never been able to articulate what it feels like to lose a friend until now. Hope this song gives you some comfort if you’ve ever felt the same way.”
