Arcade Fire, whose last album was 2017’s Everything Now, might be teasing some new music — according to some cryptic postcards sent in the mail to fans. Earlier today, a fan posted a picture of the postcard bearing the band’s logo on Reddit. “Received this in post today,” wrote user BordonGrown. “Black box covering my address. Logo at the bottom looks like the band… Anyone else received one?” The front of the postcard features a musical notation and the words “we missed you.” Another fan even set the notes to music on guitar and posted the resulting tune to SoundCloud.
