The Polyphonic Spree

I keep running into The Polyphonic Spree--on soundtracks, that is. Eternal Sunshine for the Spotless Mind marked the first time I heard their song Light & Day, which I believe was also in an iPod commercial before it showed up again in the film Murderball. Yesterday, we saw Thumbsucker and half the songs were Spree songs. I'm not sure what to call this white-robed 25-person group (a band or a choir?) but they're certainly unique and talented enough to be worthy of a blog plug. Check 'em out.
