Arcade Fire closed their headlining set at Coachella with a cover of Blondie’s “Heart of Glass” with Debbie Harry jumping on stage to share vocals with Regine Chassagne. Harry also hung out for the set-closing “Sprawl II (Mountains Beyond Mountains)” before departing. Over the band’s last few shows they have worked in a cover of the Blondie classic, this time sharing the stage with Harry.

Blondie did not perform at Coachella (they are scheduled for several festivals this summer) but Harry found herself on the grounds on the final day of the first weekend. The second weekend of Coachella will kick off on April 18 and will be available to view on AXS TV.
