Billie Eilish’s big brother and collaborator has announced his debut EP. The 22-year-old multi-instrumentalist will release Blood Harmony on October 4.

Take a listen to the first single “Shelter” below. He definitely has a different sound than his sister.

Of the song, FINNEAS said in a press release that he “wrote this song a couple years ago and just let it percolate for a while, seeing how it would age. When I looked through my music to release this year, I came across the demo and was pleasantly surprised to find I still liked it. Usually, I get bored of my stuff almost immediately. I wanted this song to have an urgency to it when I recorded it, the same way that the lyrics do —the kind of feverish feeling that accompanies loving someone.”
