Organ Playing 639-Year Version Of John Cage's "As Slow As Possible" Changes Chords For The First Time In Two Years

In 1987, the legendary experimental composer John Cage published “ORGAN2/ASLSP (As Slow As Possible),” a piece for organ designed to be played, you guessed it, as slow as possible. It was an adaptation of a similar composition Cage wrote for piano in 1985. The premiere performance in 1987 lasted 30 minutes.
