The Olivia Tremor Control - The Opera House (1997)

The highfalutin lo-fi interactivity that Olivia Tremor Control first explored with the ambient bonus disc included on early pressings of Dusk at Cubist Castle reached its apex with the vinyl version of "The Opera House." A quadraphonic odyssey spread across two 7"s, each featuring the titular psych-pop nugget that leads off Cubist Castle backed with differing musique concrète experiments clocking in at just under 15 minutes apiece, the presentation allows for listeners to create unique songs by playing back the records simultaneously in various temporal combinations and RPM speeds. Similar in conception to the Flaming Lips' Zaireeka, "The Opera House" requires three turntables for maximum mindf*ck action, but the extra effort is worth it. Like those old "Choose Your Own Adventure" books on which kids of the '80s grew up, the paths and possibilities "The Opera House" lays out are endlessly labyrinthine and completely immersive.
