Every year for the past decade, The Polyphonic Spree has celebrated the holidays with a special “extravaganza” in Dallas, featuring dancing, DJs and, of course, the band performing seasonal songs. This year, The Polyphonic Spree celebrates the 10th anniversary of that extravaganza with a live tour of the show, as well as a new CD called Holidaydream. The group also has this beautiful new video for one of the album’s standout tracks: John Lennon’s “Happy Xmas (War Is Over).” [Source]
