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. The Polyphonic Spree (above, covering Neil Young’s “Heart of Gold” for the A.V. Club) have recently been playing songs from The Rocky Horror Picture Show (stream it below), but their fourth studio album, Yes, It’s True, arrives next month. So perhaps you’ll hear some of the new tunes when they play Music Hall of Williamsburg tonight and The Bowery Ballroom tomorrow.
