Percussion music is revolution. Sound and rhythm have too long been submissive to the restrictions of nineteenth century music. Today we are fighting for their emancipation. Tomorrow, with electronic music in our ears, we will hear freedom. At the present stage of revolution, a healthy lawlessness is warranted. Experiment must necessarily be carried on by hitting anything-tin pans, rice bowls, iron pipes-anything we can lay our hands on. Not only hitting, but rubbing, scraping, making sound in every possible way...What we can't do ourselves will be done by machines which we will invent.
John Cage
