The band first teased the song's release through a tweet on 15 June 2017. A 15-second teaser was posted, along with the song's details, including its release date.[2]
Music video
The music video was released alongside the single, and was directed by Stevie Russell, who also produced the music videos for the band's previous singles "Honest", "High Hopes" and "All I Want".
"It was such a pleasure to work with Stevie again, every time we read one of his scripts they jump right off the page. We can't wait for everyone to see what he's done for 'Brother', he really captured the perfect vibe again," the band said in a statement.
Robin Murray of Clash magazine described the video as "a highly moving, touching, directly emotional affair, one that taps into the core of the song."[3] Rob Copsey of Official Charts Company described it as "emotional".[4]
Critical reception
Robin Murray of Clash magazine wrote: "'Brother' has all those key Kodaline components - moving lyrics, and a soaring chorus."[3] Rob Copsey of Official Charts Company called the production from Two Inch Punch and Stephen Harris a "nifty new production", and wrote that the song is "the rousing and emotional Kodaline you'll probably already be familiar with".[4]
