Irish rockers U2 have teamed up with Dutch DJ and producer Martin Garrix to release Fireflies, a new single that was premiered during Garrix’s headline set at Tomorrowland festival last weekend.
The show featured a surprise appearance from The Edge, who had previously collaborated with Garrix on U2 tracks such as 2019 hit We Are The People and Scars, which features on the band’s latest EP, Easter Lily.
“We go back a long way with Martin, and there’s always a sense of adventure whenever we get together,” The Edge said.
“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. It reminded me of why I love playing outdoors. I like it better when there’s no ceiling.”
The single comes as U2 gear up for the release of their first original new album in almost a decade. Timeline details are hazy, but rumours suggest a new record by the end of the year.
The band recently released a rousing music video for new track Street of Dreams, filmed in Mexico City with original drummer Larry Mullen Jr. back behind the kit having recovered from the major back and neck surgeries that caused him to leave the group temporarily.
It’s unclear whether Fireflies will feature on U2’s forthcoming record, but either way, it’s clearly a meaningful release for everyone involved.
“Fireflies has a very unique mood. It’s a special song we started working on six summers ago,” Garrix said. “It felt electrifying and very surreal to finally debut it at Tomorrowland with The Edge.”
He added: “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. It has been an absolute honour to work with them again.”
