Helicopter String Quartet

In one of the most certifiably eccentric musical events of the late 20th century, German composer Karlheinz Stockhausen designed and executed the concept of having four members of a string quartet playing an original piece by Stockhausen in four separate helicopters, all flying through the air simultaneously. The sound was then routed to a central location and mixed together; the work premiered, in turn, at the 1995 Holland Festival. Frank Scheffer's film Helicopter String Quartet depicts the behind-the-scenes preparations for this event; Scheffer also conducts and films an extended conversation with Stockhausen in which the creator discusses the conception and execution of his composition and then breaks it down analytically.
