The band's new breakup-themed single precedes their extensive November tour across eight UK and Ireland venues.
Keo have shared details of new single 'Thorn', alongside announcing their biggest headline tour to date.
The track explores themes of post-relationship reflection, with frontman Finn Keogh explaining: "'Thorn' is a breakup song - the original name was literally 'Hate', which I think says it all. It's about that period straight after a relationship ends when it's completely consuming. You start seeing someone's true colours and feel like you wasted years of your life on them, they weren't who you thought they were."
Following their appearance at The Great Escape, the band will embark on an extensive UK and Ireland tour later this year.
