Fontaines D.C. Have Never Had a Guest on an Album. ROSALÍA Is the First.

Fontaines D.C. have built four albums without a guest credit. That changes with “Where Is Gone?,” a duet with ROSALÍA and the first collaboration to appear on one of their records. It is also the third preview of Dopamine Chamber, out Oct. 16 on XL Recordings.

Produced by James Ford, the track follows “Marianne” and “Tongue,” and it continues the widening that began with 2024’s Romance. Grian Chatten and ROSALÍA overlap and trade lines over orchestrated backing, which places it further from the band’s guitar-first instincts than either earlier single.

Guitarist Carlos O’Connell framed the pairing through inheritance rather than strategy. He said he has admired ROSALÍA since her debut album, drawn to how she keeps a Spanish tradition of music alive, “which in a spiritual way felt akin to what we’ve tried to do with Irish music.” He added that, for someone with roots in both countries, seeing it has been beautiful.

Her standing among established acts is visible elsewhere this year. U2 named a song “The Mirror Maker” after her on Carnaval De Luz, though she does not appear on it. Bono told Rolling Stone that the band usually writes about people in jail or dead heroes, and that this one was simply a celebration of an artist.

The band’s own scale is shifting too. Fontaines D.C. have announced their largest headline run so far, arena dates across the U.K. and Europe through the end of 2026, then outdoor and stadium shows in 2027. Two days after the album arrives, they play London’s Roundhouse in support of the suicide prevention organization CALM.
