Before Arcade Fire released their Reflektor album last year, they aired a TV commercial that had a short clip of a song that didn’t end up on the final version of the album. Now, a muddy bootleg live version of the track, which may or may not be called “Get Right,” has made its way to the internet. If the song, which the band played live in Canada a couple of times last year, had made the album, it would’ve easily been the bluesiest thing on there. It’s a skeletal, synth-laden groove that eventually explodes into something heavier. Listen below.
