Through all the years of Austin City Limits, there probably has never been a night quite like this. From the opening processional through the crowd, through the harp solos, cymbal crashes and rousing choruses, the many members of Polyphonic Spree, all wearing their floor-length choir robes of every color in the rainbow, lifted the show to new heights on that sultry night in August, 2004. It all began four years earlier inside the head of Dallas punk rocker Tim DeLaughter, but not even he knew where his imagination would take him.
