Pronounced “666 (upsidedowncross),” “666 ʇ” is, appropriately, the sixth track on Bon Iver’s third album, 22, A Million. It contains an electro beat, warm guitar riffs, and backseat horns perfectly blended with Vernon’s falsetto.

The band played an earlier version of the track at the first annual Eaux Claires Music and Arts Festival in July 2015, and then officially unveiled the final version of the track (alongside the rest of 22, A Million) at the festival’s second edition the following summer.
