Famous quotes containing the words channel and/or classical:
“There is the falsely mystical view of art that assumes a kind of supernatural inspiration, a possession by universal forces unrelated to questions of power and privilege or the artists relation to bread and blood. In this view, the channel of art can only become clogged and misdirected by the artists concern with merely temporary and local disturbances. The song is higher than the struggle.”
