It’s been a long while since we’ve heard an album from the Polyphonic Spree, the robed and vaguely cultlike Texan indie rock ensemble whose overwhelming festival performances were inescapable in the ’00s. Psychphonic, the band’s last album, came out seven years ago. Today, though the Polyphonic Spree have announced two new albums: One that’ll arrive Friday, and another that’ll come out this fall.
