U2 and Martin Garrix officially release soaring collab ‘Fireflies’: “There’s always a sense of adventure whenever we get together”

U2 and Martin Garrix have officially released their new collaborative single ‘Fireflies’ – you can listen to it below. The band’s guitarist, The Edge, debuted the track with the Dutch DJ and producer during the latter’s set at Tomorrowland last week. “‘Fireflies’ has a very unique mood and it’s a special song we started working on six summers ago. It felt electrifying and very surreal to finally debut it at Tomorrowland with The Edge,” Garrix explained upon sharing the studio version today (Friday July 24). “I’ve worked with Bono and Edge before, but working with the whole band I got to get a glimpse of their chemistry and why U2 are who they are. They are incredible friends and collaborators, and it has been an absolute honour to work with them again.” The Edge added: “We go back a long way with Martin, and there’s always a sense of adventure whenever we get together. “Playing Fireflies for the first time at Tomorrowland, in front of one of the most passionate festival crowds anywhere, was such a rush… in fact I might have enjoyed it a bit too much.
