The Polyphonic Spree is a self-described "choral symphonic rock" group from the Dallas, Texas area. The band generally consists of a 10-person choir, a pair of keyboardists, as well as a percussionist, drummer, bassist, guitarist, flautist, trumpeter, trombonist, violinist/violist, harpist, French horn player, a pedal steel player, theremin player, and an electronic effects person. Individual members and the number of musicians vary because of the flexibility necessary in travelling with such a large band. Tim DeLaughter is musical director and contributes lead vocals, as well as keyboards, guitar, and percussion.
