Fontaines D.C. bringing in Rosalía for their first ever guest spot is quite the statement, isn't it? The Dublin lads have built their whole thing around that distinctive band chemistry, so inviting someone of her calibre onto a track suggests they're feeling pretty confident about where they're headed on album five. We're curious to hear how those two worlds collide on "Where Is Gone?" because Dopamine Chamber's already shaping up to be a proper listen when it drops later this month, and a collaboration like this could pull some new ears towards them.
