"John Cage's disdain for records was legendary. He repeatedly spoke of the ways in which recorded music was antithetical to his work. In Records ruin the landscape, David Grubbs argues that, following Cage, new genres in experimental and avant-garde music in the 1960s were particularly ill suited to be represented in the form of a recording. These activities include indeterminate music, long-duration minimalism, text scores, happenings, live electronic music, free jazz, and free improvisation."
