Dallas symphonic pop group the Polyphonic Spree are less a band than a happening, in the 1960s sense of the word. When the group takes to the stage for a live performance, its two dozen members are costumed in flowing robes of snowy white, an appropriate backdrop for their happy and uplifting musical message that's catchy pop minimally laced by gospel. Fans have compared them to both the Flaming Lips and the Beach Boys, with a smidgen of lively +Godspell-like attitude thrown into the mix. The Polyphonic Spree were founded by Tim DeLaughter, who led Tripping Daisy until 1999, when a drug overdose killed his bandmate, guitar player Wes Berggren.
