Helicopter String Quartet
Spectacle Theater (124 S. 3rd St., Brooklyn)
9:30pm both days
Frank Scheffer’s cerebral 1996 documentary explores the late 20th century’s most astounding and challenging feat of composition and performance through intimate access to Stockhausen’s process. Part Fitzcarraldo, part Apocalypse Now, and thoroughly avant-garde in both form and content, Helicopter String Quartet is one of the most mindblowing films from the world’s preeminent documentarian of 20th and 21st century experimental composers.
