From Jay Z to Justin Bieber to Drake, there were plenty of megastars making surprise appearances during the first weekend of Coachella 2014.

Sure, Hova killed it onstage with Nas and Drake was in top form with Jhene Aiko, but Arcade Fire deserve special recognition for choosing someone other than a contemporary chart-topper to join them onstage during their Coachella-closing Sunday night show.

An hour into their raucous, dance-tastic set, singer/multi-instrumentalist Régine Chassagne pulled Debbie Harry on stage while her husband, frontman Win Butler, began playing the opening notes of Blondie's signature song. The always-incredible punk icon lead the Canadian collective through a joyous live version of "Heart of Glass," which was a fitting song for AF to cover: Like Reflektor, that single is a glorious, inventive negotiation between rock and disco.

Instead of ending the incredible collaboration there, Arcade Fire segued "Heart of Glass" into their own "Sprawl II (Mountains Beyond Mountains)," and Debbie gamely stuck around to sing backup for Chassagne. Watch the whole thing below.

A few songs later, Arcade Fire sent festival-goers off into the night with a massive sing-along to "Wake Up," but that Blondie/Arcade Fire one-two punch was the highlight of their set. We can't wait to see what surprises they have in store for the second weekend of Coachella.
