John Cage, Frank Scheffer, Nikolaus Lehnhoff & The Ring in 4.24 Minutes.

In 1987 John Cage commissioned Frank Scheffer to record Nikolaus Lehnhoff's Ring at the Bayerische Staatsoper. Of course, being both Cage and Scheffer this was not to be a straightforward recording. Instead, the entire cycle was to take the form of a short experimental film lasting only 4.24 minutes. Using single frame technique, Scheffer referred to the I Ching to decide, by chance, when to take each single frame. This fascinating recording can be seen below.
