Marshall Amplification

Although John Cage occasionally worked in large, sophisticated studios - for example, when he composed Fontana Mix in 1958 - his approach to electronic and tape music was often uncomplicated, makeshift, and pragmatic, employing simple tabletop devices: tape machines, phonograph cartridges, contact microphones, record players, portable radios, etc.
He developed a soundworld that was utterly new, radical and demanding. It heralded the age of the loudspeaker, mass communication and Marshall McLuhan's 'global village.' The hiss, crackle and hum of electronic circuits,
and the disembodied sounds, snatched by radio from the ether, spoke of the 20th century.
