Tim DeLaughter and his robed 24-member choir can count a new convert to the musical movement that is the Polyphonic Spree: actress Talia Shire (Adrian, of Rocky fame), who grooved, bounced, and chanted along to the band from the core of what can only be described as a “Come to Jesus” pit, which had formed at Hollywood’s Henry Fonda theater on Friday night. Shire was there to see her son Robert Schwartzman’s band, Rooney, share the bill. (Shire, pictured with Schwartzman, also makes a cameo in their video for “When Did Your Heart Go Missing?”.) But clutching a just-bought copy of the Spree’s latest album, The Fragile Army, she was clearly impressed with the co-headliners. “It’s like watching Hair,” she told us as the Spree segued from a killer cover of Nirvana’s “Lithium” to the psychedelic (and hence, Hair-like) “It’s the Sun.” “It’s like a spectacle… they’re so theatrical and visual, this should be on Broadway or, even better, an open-air stage.” Ah, always the thespian. Besides, if the Flaming Lips can do it, why not this indie rock collective?
