Silence
Silence, A Year from Monday, M, Empty Words and X (in this order) form the five parts of a series of books in which Cage tries, as he says, "to find a way of writing which comes from ideas, is not about them, but which produces them." Often these writings include mesostics and essays created by subjecting the work of other writers to chance procedures using the I Ching (what Cage called "writing through").
