"Just mention the word Amougies, and fans of Pink Floyd and Frank Zappa will immediately know what you are talking about. This was going to be the first ever rock festival in France. Europe's answer to Woodstock. It was originally going to take place in or near Paris, but French authorities forbid it and the marquee was eventually set up a few miles outside the French border, on Belgian soil and held at Mont de I'Enclus in Amougies in the Tournai municipality. The Actuel festival was organized by the publication of the same name in collaboration with the BYG record label. It took place over 5 nights, entertaining an audience of 15-20,000 to a unique mixture of progressive pop, free jazz and contemporary music including Pink Floyd, Ten Years After, Colosseum, Aynsley Dunbar, Freedom, Keith Relf's Renaissance, Alexis Korner, Don Cherry, Nice, Caravan, Blossom Toes, Archie Shepp, Yes, Pretty Things, Chicken Shack, Sam Apple Pie, Pharoah Sanders, Soft Machine, Captain Beefheart, East Of Eden, Fat Mattress, and many more. Frank Zappa was present at the festival in a twofold capacity. First, as Captain Beefheart's road manager; secondly, as M.C., assisting Pierre Lattes, a famous radio/TV presenter at the time (and the pop music editor for Actuel magazine). The latter task proved problematic given Zappa's limited French, the prevailing language among the audience, who themselves didn't seem to understand much English. Instead, Zappa relinquished his M.C. job for one of occasional guest guitarist. He plays with almost everybody, especially with Pink Floyd, Blossom Toes, Archie Shepp and Aynsley Dunbar, a fabulous drummer he will hire shortly thereafter. He introduces his friend Captain Beefheart and provides a powerful stimulant to all the other musicians. Most legendary, of course, is Frank Zappa's jam with Pink Floyd on a very extended "Interstellar Overdrive". The festival was filmed by Jerome Laperrousaz, and the film was to be called MUSIC POWER. Due to objections from various bands (most notably Pink Floyd) whose permission hadn't been properly secured, the film was never officially released."
