Famous quotes containing the word disc:
“Perhaps all music, even the newest, is not so much something discovered as something that re-emerges from where it lay buried in the memory, inaudible as a melody cut in a disc of flesh. A composer lets me hear a song that has always been shut up silent within me.”
—Jean Genet (19101986)
