Is sheet music silent music?

The Fiery Furnaces’ next album will consist of instruction, conventional music notation, graphic music notation, reports and illustrations of previous hypothetical performances, reports and illustrations of hypothetical performances previous to the formation of their hypotheses, guidelines for the fabrication of semi-automatic machine rock, memoranda to the nonexistent Central Committee of the Fiery-Furnaces-in-Exile concerning the non-creation of situations, Relevant to Progressive Rock Division, conceptual constellations on a so-to-speak black cloth firmament, and other items that have nothing to do with the price of eggs, or milk, or whatever the proverbial expression ceased to be.

In other words, a Silent Record.

Since bands can no longer sell audio, FF decline to provide it.
