When a Tripping Daisy bandmate overdosed in 1999, it affected frontman Tim DeLaughter in more ways than one. For starters, it led to the breakup of the group, but the death also prompted DeLaughter to find religion in places other than a church, like the trees and the sun. And then, along with Tripping Daisy bandmates Jeff Bouck (percussion), Mark Pirro (bass) and Bryan Wakeland (drums), he formed the massive chamber-pop group the Polyphonic Spree. The new band began as just 12 musicians before soon blossoming into a 24-piece, with a 10-person choir, wild stage shows, some electronic effects and DeLaughter as the musical director and lead vocalist. On their recently released Holidaydream: Sounds of the Holidays, Vol. One (stream it below), the Polyphonic Spree go with fairly traditional covers of many of the classics, while still managing to put their own trippy psych-pop spin on tunes like “Do You Hear What I Hear?” and “Silver Bells.” And you can expect to hear plenty of that holiday cheer during one set, plus a healthy dose of rock in the second when the Polyphonic Spree bring their Holiday Extravaganza tour to Webster Hall on Saturday.
