The Polyphonic Spree "Silver Bells" (feat. School of Seven Bells)
Psychedelic, robe-wearing pop symphonists the Polyphonic Spree have been counting down the days until Christmas and their 13-day Advent calendar of holiday treats ends today with "Silver Bells."

The Spree team up with New York indie popsters School of Seven Bells — to sing about bells, obviously.

This rendition is pretty dreamy and meanders a bit, which fits well with the bizarre, trippy montage of Christmas imagery and two kids in what looks to be an abandoned spaceship.
