Arcade Fire recently visited BBC Radio 1’s Live Lounge. During their in-studio session, the Canadian indie rockers performed “Everything Now”, off their upcoming album of the same name. They also debuted a rousing cover of the Lorde single “Green Light” while backed by a youth choir. At one point, as Pitchfork points out, Arcade Fire frontman Win Butler thanked “our Lorde” for “fighting the good fight.”

Footage of the session will be revealed later today; in the meantime, there are a few short clips below. Audio of the program can be heard here (the Lorde cover comes around the 2:25:05 mark).

Arcade Fire’s Everything Now arrives July 28th through Columbia Records; previously, they released the music video for “Signs of Life”. “Green Light” is off Lorde’s sophomore LP, Melodrama, which is out now.
