Every band has its biggest fans. The '90s slacker/alt rock group Pavement is probably the greatest, most vital musical group in existence to someone, but right from its opening frames, Alex Ross Perry's Pavements deflates the grandeur of this idea, sarcastically overstating the band’s stature in its opening text. In an age of musical biopic plenty, this semi-ironic, postmodern take — which runs through Perry's part drama, part documentary, and part mockumentary — may be just what the doctor ordered.
