U2 are back with their first new song in two years – listen to “Atomic City’ and watch the accompanying music video below.The Irish band have returned to the post-punk of their heyday with a stirring guitar hook reminiscent of their 1983 hit ‘Sunday Bloody Sunday’ and a chorus that channels Blondie.Vocalist Bono sings about freedom (“I’m free/ I see what’s in front of me/ And your freedom is contagious/ What you’ve got I wanna be,”) and nods to “Atomic City” aka Las Vegas, the city in which the accompanying music video is set, as somewhere to find it.It’s not known whether the song, which is U2’s first since 2021 when they released ‘Your Song Saved My Life‘ for the Sing 2 soundtrack, will feature on an as-yet-unannounced album. The band have teased a record that prioritises a “guitar music” sound.The new single was produced by Jacknife Lee and Steve Lillywhite and recorded at Sound City in LA.
