Might what we know as Disco actually contain hidden meanings, despite attempts by revisionist to re-shape it as as a misunderstood culture of protest? Through interviews with the likes of Gloria Gaynor, The Village People, Kool and the Gang and others, along with a goldmine of stock footage and speculative reenactments, The Secret Disco Revolution presents a comical investigation into disco and its "mysterious longevity."

The Canadian-produced feature documentary was directed by Jamie Kastner; it'll premiere at the Toronto International Film Festival next month.
